Compress the Golf Ball

One of the most important aspects of great ball striking is compressing the golf ball. Now, we've all heard that statement and we know the feel of a purely struck shot, but what really is compression and how can we do a better job with it? Let's start by understanding the photograph below. This is a simulated shot where the clubface is just about to reach the back of the golf ball. The red line indicates where the loft or upward face angle is at impact and the blue line indicates the direction the clubhead is travelling during impact. The white line connecting the two represents the amount of compression "experienced" by the golf ball.

The narrower the gap or closer the two lines are the more compression will be exerted onto the golf ball and assuming a decent strike and appropriate launch, the ball will travel further. TrackMan refers to this gap as spin loft and without being too detailed it is the difference between where the face points at impact and where the clubhead travels at impact.

Fredrik Tuxen - one of the founders of TrackMan refers to spin loft as compression itself. To get a better understanding of how the numbers work let me give you a few examples: Jack hits a 5 iron with the face pointing at 16 degrees and the clubhead moving 2 degrees down. Bob swings at the same speed as Jack with his 5 iron and he gets the face pointing 15 degrees up and the clubhead moving 6 degrees down. Jack has a spin loft of 18 and Bob has a spin loft of 21. Both shots are hit well, so which goes further? Jack's does because he has a narrower spin loft gap and thus compresses the ball more than Bob. What spin loft would create the maximum compression? Zero! However, as we will learn spin loft is in large part responsible for the amount of spin imparted on any shot and a golf ball needs some spin to keep it flying in the air. I have found that a spin loft of 11 is very good for a driver.

Some interesting points about compression or spin loft:

  • Hitting down will not increase your compression of the golf ball or the spin on the shot. Invariably this only leads to a shot where the face angle and the clubhead direction both move downward - there is no change in spin or increase in distance.
  • A higher spin loft increases spin and generally slows down ball speed.
  • If you have similar swing speed, but hit your shots far shorter than your playing partners - this is due to a lack of compression on your shots.
  • Shots with a lower spin loft will curve in the air more easily than shots with less compression. That's why it's easier to keep a 7 iron straighter than a driver.
  • Custom club fitting can help to improve your spin loft simply by delofting either your irons or driver.

Now that we really understand what true compression is we can start to look at methods to help us improve our own ball striking. There are two ways we can compress the ball better - deloft the face angle more at impact without hitting down any more or hit down less without increasing the the loft of the face during impact. Ideally we need to deloft the face without hitting down any more. Notice how in the Jack and Bob example I used above - Bob's face was delofted more than Jack's, yet he hit down more and this limited his ability to compress the ball.

To get a good sense of what is required:

  • Get in front of a mirror with a 7 iron.
  • Grip the club and facing the mirror get the clubhead about 3" off the ground two feet back from where the ball would be.
  • Now slowly glide the clubhead through impact while maintaining the 3" space between the clubhead and the ground noticing that as you go beyond impact how much your hands need to stay in front.
  • When you start hitting balls - start small and hit soft shots off of a tee.
  • There should be no ground contact, try to leave the tee in the ground and see how low you can hit these little 7 iron shots.

This is the feel you want! Delofting the face without slamming the club into the ground. And believe it or not this applies to the driver as well. I know it may sound strange and it took me a while to wrap my brain around this, but it is entirely possible to hit up on the ball with the handle/hands in front of the clubhead.

If you have gained something from this article please share it with a friend. Let's be honest, they could most probably do with the help....

Orlando PGA Show 2013

I have just returned from the 2013 PGA Show in Orlando and as per usual it has fired me up for the upcoming year. I'm not sure what happens, but I am always motivated and excited to get down to providing a better, more informed product for my students by the time I leave.

This year was my best show for education and networking purposes. I attended my second TrackMan University workshop where TrackMan founder Fredrik Tuxen shared some invaluable knowledge. Here I also met Jeff Ritter, Terry Rowles, Martin Chuck and Josh Zander - already great teachers looking to broaden their knowledge base with TrackMan data.

I also attended the very first (of many I believe!) Facebook Golf Teaching Professionals Live Forum on Wednesday night. Talk about a loaded room - there were 150 of the brightest and most cutting edge minds in the game in attendance. From fitting to fitness, from old school to cutting edge and from scientist to psychologist, they were all there. The evening made for great theater and was very well moderated by Nick Chertock, Chris Como and Michael Michaelides.

On Thursday the actual show got started and I spoke to and met some extremely smart people. They included, but were not limited to: Brian Manzella, Joseph Mayo, Kirk Oguri, Tim Cutshall, Tom Patri, Lorin Anderson and Mike Shannon. I have a tremendous amount of respect for all these folks and their expertise in their field is second to none.

On Thursday night I attended my first TweetUp. Ten years ago I would never have thought I would go to a strange place to meet up with strange people I had only met and conversed with online, but here I was hanging out with a large group of extremely talented instructors and I had a blast. If you do not currently use Twitter I would encourage you to get going and once you do hit me up for who to follow. I have learned so much from my affiliation with these teachers through Twitter this year! Thanks to Sara Dickson and Mike Fay for setting this up - I wish I could have stayed longer.

All in all I felt like a learned more than I ever have at the PGA Show and I am inspired to go out and do more research and do a better job for my students than ever before. I am really looking forward to a fantastic 2013 - stay tuned....

TrackMan vs Flightscope

My good friends Tim and Simon Cooke from GolfPrep on Hilton Head Island recently brought their new Flightscope X2 out to Berkeley Hall. Our objective was to learn more about the numbers that TrackMan and Flightscope are putting out and we wanted to get a sense of how well one machine performed relative to the other.

I have pondered the best way in which to convey my findings and have finally committed to just simply jotting down my thoughts. My intent is certainly not to create controversy or confrontation - these are simply my own honest impressions from the day. Please also keep in mind that I am a TrackMan owner and supporter and no matter how I attempt to remove my bias I doubt whether I am able to remove all of it...

  • Prior to the test I had been having trouble with my TM unit giving unusual spin numbers every 30-40 shots, something it had never done before. As a result I had contacted TM support and was informed that I more than likely had a bad USB cable. I was also informed that the classic indicator of a bad cable would be a "double" or "half" spin. Sure enough during the test TM gave out three spin numbers from the 60 shots we hit that were right around double what the FS reported. I have since replaced the cable and have yet to see a spin rate that seems odd.
  • As you peruse the following thoughts keep in mind that good players , which all three of the test subjects were,  are very good at controlling the direction the clubhead travels (angle of attack and club path) from shot to shot. The direction may not be ideal, but better players are consistent with clubhead direction. That means that dramatic changes in either of those categories, along with sizable changes from shot to shot in club speed, were going to draw my attention and raise a red flag.
  • Since running the tests I have spoken to many "in the biz" people about radar interference. It was mentioned that the machines, when set up side by side as we had them, will occasionally give corrupted data due to the influence of the outside radar. I have not run enough tests to ascertain if this is or is not the case, but during the testing the FS seemed to give a few numbers that were incorrect and this could be due to the TM being directly alongside the unit. The TM did not do anything different to what it normally does as it seemed to be unaffected by the additional radar.
  • If a shot off turf has a decent size divot TM will only provide ball data and no club data, whereas FS reported both ball and club data for just about every shot hit off the ground. On the occasions that FS reported club data and TM did not the numbers did not look correct - meaning the attack angle and/or club path seemed to be too far from what the subject would normally generate. We hit numerous 50 yard pitch shots and TM did not offer any club data while FS reported for most of these shots. The problem was that the club path was said to be almost 15 degrees from in to out along with a spin rate of 14,000 rpm - just not happening! I actually preferred that TM did not provide club data as I would rather have no information than have to explain away improper information. That being said I would love a radar that provided correct club data on all shots.
  • With both units unplugged and PC's powered down the TM (2:05) was aligned and ready to roll in about half the time of the FS (4:16). I was told that with an iPad the FS can be aligned and operational in far less time.
  • We noticed that both machines reported different Swing Plane numbers when they were moved (flipped positions) relative to the same golfer. I have tested this before and the changes in data are due to the hardware in the TM II. Each machine appeared to provide better data when the golfer is hitting shots aligned with the center of the unit - something that was not possible when running two machines.
  • We tested the ability of each unit to report gear effect, by logging the point of contact on certain drives and then comparing each units Face to Path and Spin Axis numbers. The TM reported gear effect as I would have anticipated and most of the time FS reported along similar lines. However the first shot we examined, a big heel hit, was actually reported by FS as being a slight toe side hit. TM reported a Face to Path of -9.3 and a Spin Axis of -5.4 while FS reported a Face to Path of -2.2 and a Spin Axis of -11.0
  • I was amazed at how closely aligned the Spin Rate numbers were for each machine. Unless there were dramatic differences the spin rates were almost always within 100 rpm's.
  • There seemed to be quite a few instances during the testing where the attack angles were not even in the same ball park. I had nothing to help me determine which machine was correct, other than the aforementioned fact that better players tend to be very consistent, and all too often it was FS reporting wide ranges of variation from the player.

Keep in mind that my intent is merely to report what I observed and not to offend anybody or any entity.  I could tell that Tim and Simon were a little concerned with the results and they went home and performed additional tests. I am happy to report that the FS performed much better without the influence of additional radar and when shots are hit from the center of the unit. Tim's follow up comment to me was:

I believe that side by side testing, although seeming to be a good idea, does not work.  Clearly there was some radar interference at work as the inconsistent numbers were not reproduced in stand alone tests.  Maybe the only way you can really compare the units is with extreme high speed cameras with the units working independently of one another.

I would have to agree with Tim's sentiments and I have started to make plans to have each unit test the same golfer on the same day, but without the potential interference of outside radar.

You know I'll report back on that one....

Anchors Away!

While I am sure you have read most of what has been written on the USGA and R&A proposed ban on anchored putting I wanted to briefly share my take with you:

Professional Golf

I'm sure the primary objective of the two governing bodies was to eliminate anchoring from the major tours and I emphatically agree. I think the best golfers should be capable of freely swinging the club with their hands and arms.

Bifurcation and Growing the Game

Bifurcation means the splitting of a main body into two parts - and that's exactly what needs to be done with the rules of golf. There may be another sport, but I cannot think of one  where the 'amateur' body governs the 'professional' body. From college football to baseball, there are different rules for the pros than the amateurs and that's the way it should be. The governing bodies should be growing the game and this ruling is going to eliminate so many ailing golfers from competing at any level or even playing the game. In 2016 there are going to be thousands of golfers who will turn down an invitation to their Member-Guest event due to the fact that they are simply incapable of putting the ball. I've seen golfers who twitch anchored putters - never mind a putter that's not attached - in 2016 they're out of golf! Come up with a ruling for professional golf and USGA/R&A events and let the rest of us just enjoy the game.

Loopholes

If you thought you had seen some strange putters and putting styles, you ain't seen nothing yet! As with anything, golfers who simply cannot putt will find ways to the job done in unique and quirky ways by the time 2016 rolls around. Ever seen anyone putt with both arms wrapped around the putter twice?

I like the idea of changing the ruling for the big guys, but don't punish everybody in order to achieve your goal...

The End.

Looking for a 'Low Spin' Driver?

This summer I had the privilege of meeting expert club fitter Ian Fraser from Modern Golf in Toronto, Canada. Ian is the most knowledgeable and passionate fitter I had been around and before long I was peppering him with all my questions and concerns regarding equipment.  One question that came up early in our discussions was spin rate off the driver. We both commented that it was far more common to encounter golfers with too much spin than too little and that led to my question, "Were there any drivers or shafts that stood out from the rest in their ability to reduce spin rates?" Remember that the optimal spin rate for just about all club speeds with the driver is somewhere between 1800-2200 rpm when supported by the correct launch angle.

With Ian's expertise I have compiled a list of the three commonly available drivers that currently do the best job at reducing spin. Keep in mind that that I said 'currently' in that, as with technology, this is a moving target and this list could change very soon.

  • The TaylorMade R-11 S: this club is far better than the original R-11 which did very little in reducing spin. According to Ian the R-11 S also ranks right up there in ball speed - she's a hot one!
  • The new Ping Anser: the newest of the three drivers, my testing shows that this may perhaps be the best at reducing spin.
  • The Callaway Razr Fit: certainly the simplest, most classic looking of the three heads. This driver also received a nod from Ian regarding a hot face.

As a side note - the new Cobra AMP driver often came up in our discussions regarding both low spin and hot heads and it seemed to be a favorite among many of my students this summer. I would give it "honorable mention" status.

Obviously very soon after discussing low spinning heads I quickly turned to shafts to see what kind of help golfers could get in that department. Here are Ian's recommendations:

So if you're a golfer who has access to TrackMan or similar radar device and you know your spin rate with the big stick is too high look into one of the above combinations to get you a few welcome additional yards off the tee. And of course, should you be anywhere near Toronto look Ian up....you will not regret it!

Ian and the crew from Modern Golf will be visiting Berkeley Hall in January, so should you be interested in a fitting please contact me to schedule a time.

Golf Impact Errors

The Moment of Truth

Impact is the most important part of the golf swing! The ball spends an average of 1/2000 of second on the face of the club, yet it is during this time that it receives it's all-important travel itinerary.  How high; how far; what curvature; spin rate; and ultimately what destination is all determined in that fraction of a second.

The above picture is an ideal impact position.

  • The weight is comforably on the front foot
  • The handle is leading the clubhead into the ball and  the clubhead is travelling slightly down for a ball-first, divot-second strike
  • The head is over the ball with the weight in front of the ball leading to body curve

There are only three errors a golfer can make at impact and here they are:

Head and Weight Back

In this example the head has worked back behind the ball too much and the weight remains on the back foot.  This  golfer scoops the ball off the turf and tends to hit weak, high fades and slices with the occasional pulled shot.  Should a divot occur it is most often before the ball is impacted.  This is a typical what I would call "weekend warrior" swing.

Head and Weight Forward

In this example the golfer has found a way t0 "squeeze" the ball and actually strike it fairly well, however, due to the upper body being positioned in front of the ball, direction is a major challenge.  Divots are quite deep and this golfers' tendencies will be to hit pull draws with the occasional push or flare.  There is not enough body curve in this mid-level impact position.

Head Too Far Back with Weight Forward

This impact position is invariably the demise of the better golfer.  Here the golfer has found a way to attack the ball from the inside while still delivering a downward blow to the ball, yet there is too much of a good thing.  The head hangs back while the hips drive to the target, dropping the clubhead too far to the inside and encouraging the hands to flip through impact.  This golfer will tend to play well with good timing, but should things get nervy they will hit blocks and quick, sweeping hooks.

Analyze your shot pattern on the golf course and start to get an idea as to which of the above categories you fall into.  Get in front of a mirror and work towards improving or tempering certain elements of your impact position.  As you do this remember feel is very seldom real when it comes to golf.  Create the correct look in the mirror and then absorb what that 'look' feels like and take that out to your next practice session.

This Guy is Really Long...

Last week I had my first opportunity to work with a professional long driver.  Having never taught one before I was not sure what to expect, but I knew that with TrackMan I could help him become more efficient and ultimately make him better at his profession. I must admit though -  I was nervous about how to go about things prior to our meeting.

The fine young gentleman I taught was Patrick Hopper - already an accomplished and successful long driver that finished in the top 10 in Remax World Long Drive Championship in 2010.

He arrived with a golf bag full of 48" drivers (all USGA spec) and after chatting for a while he shared that his tendencies were high fades and he sometimes struggled to find the grid. When he started hitting I was in shock - these were the highest and longest golf shots I had ever seen. We even had to get him to aim a little to the right so as to not rain down drives on the golfers warming up on the far side of the range over 350 yards away.  The photo below shows how much the ball actually compresses into the face before departing in a hurry....

After watching him hit about a dozen drives we took a look at his TrackMan numbers for a few of his better shots:

  • His average apex height was just over 200 feet which was massively high
  • His spin rate at 2800 rpm was high
  • While his club path was 5.5 degrees outward he tended to hit too many weaker fades which indicated a heel strike

We set out to lower the trajectory and encourage baby draws with a strike point that was very slightly favoring the toe side of the club. After some work and "chipping" a few drives at around 120-125 mph he started to get the hang of a straighter club path and an improved strike point.

Here is a comparison of his best shot before and his best shot after.....

The shot above indicates a slight toe-sided strike which was not his tendency in the early going. The shot below also indicates a similar strike point, but now with a more appropriate launch angle, better spin rate and 15 extra yards.

Keep in mind that the above shots were hit with newer Titleist NXT Tour golf balls into about a 10-12 mph headwind!

What an amazing talent this young man is - I was amazed at how calm and sincerely pleasant he was to work with. At the end of the day he received the same lesson I give golfers everyday - improved distance via better efficiency and improved accuracy via an understanding of how your swing should cause the ball to respond. Keep an eye on Patrick Hopper.

That really was fun!

Form vs. Function

Long ago I came to realize that much of modern day golf instruction is based primarily around instructor style preference. Way too much of the information being peddled is form based instead of being function based. Tommy 'Two Gloves' Gainey's win this weekend on the PGATour illustrates that there is more to a golf swing than simply what meets the eye.

In studying the top golfers of all time - no two swings are alike. Who is to say that Ben Hogan's flat plane is better than Jack Nicklaus' vertical arm move? Who is to say that Sam Snead's slight over the top move was better than Nick Price's drop down transition?

Ultimately it all comes down impact and physics - the forces and angles you are causing the club to impart on the golf ball. Impact is the one position in which all of the great players are decidedly similar. From Patty Berg to Annika and Tom Watson to Phil Mickelson - all these players assume a very similar position at impact. If this is the case, which, trust me, it is, then the appearance of the swing should play far less of a role in a golfer's path to improvement.

Here are the elements of a great impact position with irons:

  • the weight is noticeably on the front foot; 80% or more
  • the handle always leads the clubhead
  • the head remains over the ball, while the hips have shifted to the target; this creates what I refer to as body 'curve'
  • the clubhead travels down (downswing) into the ball; this includes fairway woods and hybrids

Here are two short videos to help:

The next time you take a lesson make sure your teacher works towards getting you into a better position at impact. It is the only way you are going to start hitting better, more compressed golf shots.

The Impact-Driven Golf Swing

There are many ways to swing a golf club, but only one way to hit a golf ball correctly. The whole idea behind my philosophy is the above statement. When looking at the top players of all time, there are no two golfers that swing the club the same way, however they all manage to impact and strike the ball in a similar fashion. How is it possible that Lee Trevino, Ray Floyd and Nancy Lopez can make the ball get to the target the same way that Ben Hogan, Nick Faldo and Tiger Woods do? The only answer can be impact. A position where the weight is well on the front foot, the handle leads the clubhead into the ball (with irons) while the head remains over or slightly behind the ball.

2012 'Shocking' Ryder Cup Review

Wow! What a great a great Ryder Cup and an amazing Sunday of golf. A truly stunning result and certainly one of my top five most memorable golf broadcasts. I wanted to share of few of my impressions from the week. Here goes:

  • Ian Poulter: I have always enjoyed Ian's 'confidence' - some might call it arrogance, but I've never seen it that way and I have also thought him to be a top player and competitor. Everything I believed about Ian James Poulter has now been tripled! He, (virtually) single-handedly, won the cup for Europe with his five closing birdies on Saturday. Those five holes and that win for Europe allowed them to hang on to a glimmer of hope for Sunday and without that glimmer they don't get the job done. He now owns the best all time Ryder Cup record for players who have played in at least 15 matches - that says something about IJP.
  • Phil Mickelson: While I have never been a fan of Phil, this weekend I finally packed up my things and climbed on his bandwagon. One of the coolest things I witnessed all week was Phil clapping for Justin Rose when he hit a good shot or holed a long putt. He played with fire, he played beautifully, and above all else he was a true gentleman.
  • Keegan Bradley: This guy is for real. He has tremendous heart and just like Poulter, has the make up to be a fantastic competitor for many years to come in the Ryder Cup. I did not get the benefit to the sideways look at putts and the twitchy, start stop pre-shot routine has got to go. I was glad I had the golf recorded so I could fast forward while he got ready to hit a shot....
  • Jose Maria Olazabal: It was great for Ollie to get the win and it was obvious on his face how often he thought of his friend and mentor Seve Ballesteros. Seve truly was the 13th amn and I believe his influence played a laregr than appreciated role in the European victory. I enjoyed JMO's post victory quote: "All men die, but not all men live. Today you made me feel alive again!"
  • Should Davis Love III get the blame? Completely ridiculous! If one putt or chip goes in for the US squad on Sunday the result is completely flipped and he's a hero.
  • Bubba on the 1st tee: Perhaps one of my favorite moments of the event! I got chills the first time I saw it and I hope (believe) he has started a trend in the matches that will continue for a long time. You saw him do it first! Great stuff.

  • Giving putts and conceding matches: Francesco Molinari was instructed in the 18th fairway to win the hole by Ollie. In my view there is a difference in retaining the Cup and winning the Cup. Same celebration and 'same' outcome, but winning is always better. I honestly don't think I would have given TW his putt either....
  • Spirit of the matches: This Ryder Cup was contended by two excellent teams where many of the players seemed to be in form. The matches were great theater and the players conducted themselves in a classy fashion. I did not see anything that I thought to be underhanded.
  • Sour grapes: The European team is sour when they lose and their fans claim gamesmanship and unsporting conduct when they lose (see Brookline '99). The US team and their fans are no different (see Medinah '12). Nobody enjoys losing - it's human nature and I'm okay with that.
  • Top players on each team: For the Euro squad it must be Poulter who also gets Man of the Ryder Cup in my books. On Saturday afternoon he loaded up the whole event on his back and said watch this...A nod must also go to Rory McIlroy who played some incredible golf and carried the 'World No. 1' flag beautifully. For the Americans there were a few superstars: Jason Dufner, who just continues to get better; Keegan Bradley who fired up Phil and played liked a man possessed; and Phil, who not only played with passion again, but owned the 'classy moment' of the week. Dustin Johnson also quietly went 3-0.
  • Duds: For the Euro team G-Mac and Westwood performed below expectations and for the US it can only be TW and Stricker who earned a measly half point out of 8 opportunities.
  • Was this a 'miracle' comeback? No, not really. If you run the odds on a team coming back from a 10-6 deficit going in to Sunday you come out with a 19% chance. Even though it's only happened once before, not a miracle at all.
  • Don't count your chickens: Here's an interesting piece written by ESPN's Gene Wojchiechowski on Saturday evening. Gene has been taking a beating for this one.....

In total I absolutely loved the event and it once again proves that the game of golf is in good shape. There are more than enough great players and characters to carry the game without Tiger being what he once was.

When You Play: Watch or No Watch?

1watch

Can playing with a watch on help or hurt your game? Now, other than having quick access to the time to see how late you are getting home the results of this test are a no brainer - leave your watch in the bag!

2watch

Our fitness trainer at Berkeley Hall, Derek Lemire, was down hitting a few drivers and I thought he'd make for a good subject. Derek is dangerous off a 6 handicap and has improved dramatically the last few years.

For the test I asked Derek to hit shots without a watch, with a single three ounce watch and just for kicks with two three ounce watches. He hit three shots in each condition, I would delete data for the worst shot of the three and then we repeated. The Trackman results were very interesting:

No Watch

  • Club Speed 94.6mph
  • Ball Speed 143.3mph
  • Carry distance 227.6yds
  • Total distance259.8yds

One  Watch (3 oz.)

  • Club Speed 93.5mph
  • Ball Speed 142.8mph
  • Carry distance 222.5yds
  • Total distance 249.7yds

Two Watches (6 oz.)

  • Club Speed 92.6mph
  • Ball Speed 141.2mph
  • Carry distance 218.2yds
  • Total distance 244.5yds

As you can tell there was a noticeable difference between each example and while I understand no golfer would wear two watches a Rolex or watch with a heavy steel band can easily weigh up to 6 ounces. A 3oz watch or bracelet on your wrist can rob you of as much as tenyards per tee shot.

Moral of the story: unless you are hitting the ball too far at the moment leave your watch in the bag - it can only slow you down.

Rules question: If a golfer felt like they had too much club on a par three would they be able to put their watch on, hit the shot and then remove it again? I'd love to hear from the rules gurus out there on this one....

Driver Test: Old vs. New

My wife encouraged me to clean out the garage the other day and I happened upon an old driver I used in college. I still remember how cool this driver was - it was the latest and greatest and even had a titanium shaft! When was the last time you saw one of those? Just for kicks I placed it up alongside my current Titleist driver and was shocked at the massive difference between the two - the older club looked smaller than my current three wood! How could I have possibly played well with this mini club? This got me thinking about a TrackMan test.

For the record the smaller club was a TaylorMade Burner Plus 9.5 degree with a titanium X flex shaft and my current club is a Titleist D3 8.5 with a Motore F3 70 gram graphite S flex shaft. There is a fairly substantial 1.5 inch difference even though both clubs were standard length in their day. I am not sure about the weight or the true frequency/flex of each club as I did not have the appropriate equipment to check those measurements.

For the TrackMan test I hit 12 shots with each club and deleted the data for the two worst shots. I noted that the attack angle, club path, swing direction and plane were very similar from club to club.

The primary differences seemed to be:

  • Club speed 99.7mph vs 101.8mph - I believed that this difference would be greater due to the large difference in length of shafts.
  • Ball Speed 145.7mph vs 152.4mph - I put this down to the fact that the smaller head led to more off-center hits and thus a decreased average ball speed and smash factor.
  • Point of contact - there was a noticeable tendency for me to strike the bigger club in the heel. This led to more shots missed to the right due to gear effect and an increase in the spin rate 2455rpm vs 2895rpm.
  • Height - even though the smaller club launched the ball slightly higher the apex height was lower due to less spin and ball speed.
  • Carry and total distance - the smaller club carried the ball almost 17yards shorter, but with less spin and a flatter land angle rolled further to only finish just over 10 yards short of the bigger club.
  • Dispersion - the smaller club had more shots finish further from the center line due to a much smaller clubface and substantially lower MOI.

Here are the TrackMan generated dispersion charts (yellow is the smaller club) and averages:

I was amazed at how small the difference between the two drivers, total distance wise, there was. Going in to the test I would have thought that there would be a 15 yard difference at least. I expected the smaller club to spin the ball less and lower the apex which it did, but I was truly amazed at how little distance I lost with it. I did notice a much greater tendency to hit the ball outside the sweet spot with the smaller club and that led to some fairly aggressive gear effect draws and fades.

Driving is not my strong suit and I am always looking to keep the ball in play off the tee. Armed with this new knowledge I am going to try a shorter shaft in my current driver head and see what that does for my fairways hit statistic. I also plan on practicing with the older club - I think it is vital in improving ball striking to practice with smaller headed clubs.

I also think this test might also illustrate that the majority of the distance gains we see on the PGATour today are not equipment based, but primarily due to the ball.....your thoughts?

Testing Mudballs....

I recently decided to test a widely held philosophy that mudballs curve a certain direction - if the mud is on the left, it is believed that the ball will curve to the right. Essentially the ball will curve away from the mud....

As you might imagine it is quite difficult to purposely attach mud to a golf ball. In order to keep things fairly consistent I rolled a small strip of duct tape into a ball and then taped over it to keep it in place with additional duct tape. I primarily wanted to create a scenario where the ball carried additional weight along with increased friction on one side.

All shots were hit with a seven iron and I selected the three 'best' swings for each of the options (mud on the left or right). Here are the Trackman dispersion charts and average numbers for the shots that I measured: (yellow is mud/tape on the left and white is mud/tape on the right)

The mud/tape on the left is the top line and vice versa:

The averages for the shots actually showed that the ball could curve either right or left when mud is present - regardless of which side it is located. The results were inconclusive, but I can say this - the spin rate seemed to be decreased and there were a few shots that seemed to actually curve both ways.

The coolest thing about the test was how clearly you could see the ball rotating around a fairly horizontal spin axis. With the black tape contrasting the white of the ball it was amazing how you could see the black side remaining on the side it started for the entire flight of the shot. So much for side spin!

The next time you have a mudball all you can really do is aim for the center of the green and hope for the best.

Returning to Berkeley Hall

I will soon be leaving Atlantic Golf Club and heading south for the fall and winter seasons. It has been another amazing summer of learning and growth and I look forward to returning to Berkeley Hall to resume my teaching operation there. I will be back at Berkeley Hall on Tuesday September 18th and time slots are filling up. Call me at (843)247-4688 if you'd like to come out and get firing for the fall....I have so much I want to share!

How to Hit High & Spinning Sand Shots

This shot is an invaluable tool for all golfers. We all need the high, spinner out of a bunker every now and then don't we...? This one really works and is so simple to execute you simply must give it a try.

Here are the keys to remember:

  • Set up with the weight favoring the front foot about 70/30
  • The ball should also be well forward in your stance
  • The most important part is to keep your shoulders parallel to the sand - this will most often feel like your lead shoulder is lower than it has been in the past. Keeping the shoulders LEVEL is huge
  • With the shoulders being level the hands will actually be slightly behind the ball and the face set to open
  • Pick out a spot 2-3 inches behind the ball and stay aggressive - remember this ball's going up!

Now get out there and practice....and that's it really. Could it get any more simple?

Optimal Strike Point for Longer Drives

We've all heard the saying 'high launch and low spin'.  With the help of TrackMan I have been able to learn which part of the clubface to strike the ball with in order the get the ball to launch higher, spin less and ultimately travel further. Watch the following video...

optimal strike point
optimal strike point

Here are the factors that make a slightly high and toe sided hit optimal:

Launch Angle

  • Due to the roll/curvature of the face there is more loft above the center line than below.  The static loft of the club is measured in the center of the face, so if a club has 9.5 degrees of loft that is only in the one central location.  Half an inch above the center line the loft increases by around 2 degrees and vice versa for below the center line.
  • A strike above the center line will always lead to a higher launch angle and can often be achieved quite easily by teeing the ball higher.

Spin Rate

  • Due to vertical gear effect a strike that occurs below the center line will have a substantially higher spin rate than one higher on the face.
  • I have seen increases of almost 1400 rpm with low strike points - in addition to distance sapping lower launch angles.

Gear Effect

  • Most of the golfers that I teach need to hit draws.  A golf ball that is struck on the toe side of the clubface will tend to have a greater inclination to draw than one struck towards the heel of the club.

Clubhead Speed

  • If a shot is hit out of the center of the face with a swing speed of 100mph a spot on the face 3/4" out side of that will be travelling at almost 103mph and a spot the same distance inside that will only be travelling at 97mph.
  • The ball will travel faster and most often further with higher club speed.

If you'd like to get a feel for where you are striking the ball on the face try dry erase marker or Dr. Scholl's Odor X - they both work like a charm and give instant feedback.

Next Up: The Ocean Course at Kiawah

Next up for the 2012 major championships is the PGA Championship at the Ocean Course at Kiawah.

I played the course during the summer of 2009 on a perfect day and still left feeling like it was a 'two sleeve' golf course - and that's only if you're a fairly accomplished golfer.

Take a look and see what the PGATour's best are in for...

The Science Behind Superb Wedges: Part II

In my quest to better understand pitching, chipping, and more specifically the low spinning wedge shot I needed to watch different professional players hit a variety of shots and be able to track the data from each shot.  My objective was to understand how friction or grip between the face and the ball influenced the launch angle, height and spin rate.  I have named the measurement of this grip and it's influence on the golf ball - friction launch.

I need to explain some fairly detailed physics as to how I measure friction launch, so bear with me.  The golf ball always launches somewhere between where the face is angled and where the clubhead is travelling - on both a vertical and horizontal plane.  The ball also always launches closer to where the face is angled than where the clubhead is travelling.  Where the ball launches between the face angle and the clubpath is primarily determined by club speed and friction between the face and ball.  I needed to measure this friction in order to see how it effected the trajectory and spin on wedge shots.

With the help of Mark Reilly and Edoardo Molinari, we came up with the following formula to determine friction launch:

(Dynamic Loft - Launch Angle) x 100/Spin Loft = Friction Launch

This formula informs us where the ball launches between the face and path. The percentage indicates how far below the face angle the ball launched. A friction launch of 0% indicates that there was absolutely no grip at impact and the ball launched in the direction the face was angled at impact.  A friction launch of 50% would indicate that the ball launched directly between the face angle and the clubpath and the grip was exceedingly high.  By the way - neither of these are possible under normal conditions. The smaller the percentage, the higher the launch and lower the spin and vice versa.

With all the various situations I tested I needed to keep certain factors constant in order to be able to detect why the trajectory and spin rate of each shot was altered.  My constants were TrackMan - to record the data; the golf club - a Titleist Vokey SM4 54 degree wedge; and the distance of each shot studied - 50 yards.  If any ball landed short of 40 yards or longer than 60 yards it's data was thrown out.  The factors I controlled were the quality of the lie and playing surface, the grass and dirt in the grooves and on the face and the type of golf ball.

Here are the average results attained from three professional golfers hitting 10 shots each in 7 different situations:

1. Clubface packed with dirt and grass/ProV1/off lie board (to eliminate additional matter)

  • Friction Launch 17.9 degrees/Spin Rate 4408/Launch Angle 34.9 degrees/Height 31.9ft/Carry 51.6yds

2. Clean clubface/ProV1/off lie board (to eliminate additional matter)

  • Friction Launch 28.1 degrees/Spin Rate 6501/Launch Angle 28.4 degrees/Height 25.1ft/Carry 50.3yds

3. Wet clubface/ProV1/off lie board (to eliminate additional matter)

  • Friction Launch 28.1 degrees/Spin Rate 6564/Launch Angle 28.7 degrees/Height 25.7ft/Carry 50.4yds

4. Clean clubface/ProV1/off turf/preferred lie

  • Friction Launch 31.9 degrees/Spin Rate 7178/Launch Angle 26.1 degrees/Height 22.3ft/Carry 48.9yds

5. Clean clubface/hard range ball/off turf/preferred lie

  • Friction Launch 28.8 degrees/Spin Rate 6625/Launch Angle 27.6 degrees/Height 25.1ft/Carry 50.8yds

6. Clean clubface/ProV1/off a new mat

  • Friction Launch 30.4 degrees/Spin Rate 6859/Launch Angle 26.8 degrees/Height 23.3ft/Carry 49.2yds

7. Clean clubface/ProV1/Off a tee

  • Friction Launch 30.6 degrees/Spin Rate 7259/Launch Angle 27.6 degrees/Height 24.8ft/Carry 51.2yds

Edoardo Molinari was also kind enough to submit his TrackMan data to me from the 10 shots he hit with his 60 degree wedge and 10 more with his 56 degree wedge: (the following shots were hit with premium golfballs, off preferred lies and cleaning the clubface between each shot)

60 Degree Wedge

  • Friction Launch 22.9 degrees/Spin Rate 6048/Launch Angle 36.2 degrees/Height 34.8ft/Carry 51.0yds

56 Degree Wedge

  • Friction Launch 24.4 degrees/Spin Rate 6046/Launch Angle 34.2 degrees/Height 31.5ft/Carry 50.5yds

NOTE: After a few weeks of practice Edoardo has improved his 10 shot average with his 60 degree to a spin rate of 8700rpm and a Launch angle of 26.1 degrees! There is something to this...

The deductions I took from the above tests are as follows:

  • Shots out of the rough, first cut or even into the grain lies are always going to launch higher, spin less and as a result fall out the sky faster and roll more after landing - no matter how good you or your wedge is.  There simply is too much 'matter' involved between face and ball to create optimal friction.
  • A wet clubface actually makes very little difference in determining how much friction, and thus spin, is imparted on the ball.
  • A premium golfball makes a noticeable difference with the wedges.  Not only will it add distance off the tee, but it will also allow you to hit better and more predictable short shots.
  • If the rules allow you to tee the ball up - go ahead and do so.  You increase your ability to place the clubface cleanly on the back of the golf ball.
  • Hitting pitch shots off mats is a fantasy world and can only increase the 'illusion of competence'.  No bad lies, nothing between the face and the ball, minimal consequence to heavy shots...
  • For pitch shots, higher lofted clubs do not spin the ball significantly more than the next wedge down (60*vs56*). They do, however, get the ball to stop slightly faster due to a steeper landing angle.
  • Average friction launch for a 50 yard shot is around 25%.  The lowest friction launch was out of the poorest lie (18%) and the best results came from an ideal fairway lie, a new and clean wedge along with a premium golfball (32%).
  • The quality of the lie is the most important factor in allowing a golfer to control the trajectory and spin of the wedge shot they are about to play.

Let's take a look at the factors that influence friction launch:

The Golf Club

  • The sharpness of the top edge of the groove will effect spin, yet most of the spin on a shot comes from the roughness of the area between the grooves.

  • In my opinion the wedges that provide the highest amount of spin are the models that have the roughest surface between the grooves - the new TaylorMade ATV and the Nike Vr Pro wedges seem to do an excellent job with 'between groove' treatment.
  • An excellent way to improve spin with your current wedges is to have the face sandblasted with normal aluminum oxide sand.   This will provide a rougher, more 'grippy' texture to the face.
  • The number of groove edges that come into contact with the ball also effects backspin.  In pushing the limit of the groove rules manufacturers can now put five grooves on the surface of the ball at impact versus the traditional three.
  • Grooves channel away some of the moisture and matter from rough that gets between the ball and face - but seldom all of it.
  • The grooves and face of your wedges should always be very clean - even when you're practicing.  Keep a towel or brush handy to clean the club after every few shots.
  • If you are serious about competitive golf I would recommend having a tournament set of wedges and a set you use in practice. Every shot you hit wears down the face which reduces friction at impact.
  • In fact Gary Player would ensure that his caddie never cleaned his wedge after hitting a sand shot - the sand particles on the face helped to create more friction between the face and ball for his next shot.

Turf Type and the Quality of the Lie:

  • When you are into the grain you will often get grass caught between the ball and the face, thus reducing grip.  A down grain shot will 'cut' very little grass and thus allow for clean contact and increased grip.
  • Different turf types are thicker and stronger and thus, even at fairway height, support the ball enough to keep it up and away from the grass.  This makes it easier to have a higher friction launch factor.  If you've ever played off kikuyu grass you'll know what I mean.
  • When laying up on a par five understand the value of high friction launch - lay up in the fairway and don't be greedy.

The Swing

  • This is where I am now focusing my efforts.  There does seem to be a method that DOES NOT involve a more open face, increased speed, higher launch or a cutting action that seems to produce a lower trajectory with a much higher spin rate. Stay tuned.....

Forward Shaft Lean

I love this photograph taken by Robert Beck yesterday at the Open Championship.  It reveals what it takes to hit compressed and penetrating iron shots - forward shaft lean.  If you tend to hit the ball too high with your irons or haven't taken a divot all year this is a fantastic image for you to keep in mind the next time you practice.

Remember these important points to help you get into this position at impact:

  • If you have a weak grip it is almost impossible to get here. Strengthen your grip a touch and that will encourage the hands to lead and hold through the strike.
  • Your weight must be forward at impact - favoring the lead foot 80%/20%.  Drive the hips forward in the downswing with out the head shifting in front of the ball for proper weight distribution at impact.
  • Deloft the clubface as much as possible at impact.  Top players actually launch a 4 or even a 5 iron at a height similar to that which they launch the driver.  Practice hitting low, punch type shots until you can hit the ball at head height.
