Information to improve your golf game (April 2013)

Greetings!

Big Boy Golf Club Optimization  

 
This past month I found two very interesting writeup related to how some PGA Tour players are optimizing the performance of their clubs.  This information can also help you.

Tiger Woods Driver Optimization.  In the April 1, 2013 issue of Golf World, Tiger's driver launch/spin data are noted from 2007, and from the present time.  Here is this data...
  • 2007 - 8.45 degrees launch angle, 3,343 rpm spin.
  • Now - 11.76 degrees launch angle, 2672 rpm spin. 

These changes have allowed him to maintain his driving length - 300 yard driving average, a drop of just 2 yards from 2007 - despite a loss of 4.5 mph of driver swing speed during this time period.

 

The article also noted that the 21 players in the top 20 in Tour Driving Efficiency average about 1.5 degrees more launch and 245 rpm less spin than the Tour average.  My prediction is that negative Angle of Attack and higher spin will be a thing of the past as more and more players want more distance.

-------------------- 

Gary Woodland Driver and Fairway Wood Shafts.  In the May 2013 issue of Golf Digest - the "What's In The Bag? article - it is noted that Gary plays a 96-gram shaft in his driver.  More interestingly, he plays a True Temper X-100 STEEL shaft in his fairway wood (it say "tipped out of my mind" - so very stiff).  I think the X-100 steel shaft weighs something like 120 grams or more.  This is another illustration that lighter woods shafts are not necessarily better for golfers in terms of their driver and fairway wood performance. 

 

The Truth About Adjustable Drivers - The Tom Wishon Study

In mid February, I and other club fitters had some correspondence with Tom Wishon from Tom Wishon Golf.  Tom Wishon Golf is a recognized industry leader in research into golf club design, club performance, and custom club fitting.

In one of his notes to me, he said that "... the situation with the adjustable hosel pieces is stacking up as THE number one biggest area of conflicting information that I have ever seen."  Tom mentioned at that time that he would get a number of the major OEM adjustable hosel driver heads and actually measure specs for loft, face angle, and lie angle for different settings with these heads.

Well he completed that study about a week ago, and has published the results he obtained - here is the link to his report:

     Tom Wishon Technical Report on Adjustable Hosel Drivers

The first part of the report provides details how how he made precision measurements on loft, face angle, and lie angle.  It then discusses the basics of how adjustable hosel designs work.

The most important part of the report is the measurement results he presented.  He made detailed measurements for four of the major OEM drivers being sold today.  I hope many of you can take the time to read this part of the report and his conclusions.  Here are some of the highlights that I think should be most important to you: 
  • A very large majority of the measured Face Angles for the drivers measured are Very Open - often more than 3 degrees and even in the range of 8 degrees open!  This is bad news for golfers who want help from their driver to reduce the amount that they slice the ball.  Golfers who slice need Closed Face drivers, not Open Face drivers.
  • Many of the measured driver lofts are more - often a lot more - than 1 degree different than the stated lofts for the OEM driver settings.  If you think you are hitting a 10.5 degree loft driver, you may in fact  be hitting one that has as much as 12.5 or more degrees of loft.  If you balloon your drives with one of these drivers, this could be the cause.
  • Tom's results confirmed his expectations from the start (he in fact had developed an adjustable hosel driver design in 1995) - "... you simply cannot change the loft of a woodhead through a change in the angle of the shaft using such an adjustable hosel device."
  • The design of the TaylorMade adjustable driver is actually different than the others - it has an adjustable sole protrusion piece on the sole that can in fact allow you to change loft and face angle at the same time.  For this driver there are 84 different settings that you can make for loft, face angle, and lie angle with this driver.  It is the one adjustable driver that can possibly be set up, in my opinion, to provide loft and face angle settings that can help a driver fitting.  However, you had better work with someone who Really understands what the settings will produce. 

Tom's report illustrates in detail the truth about Adjustable Hosel Driver Designs - in my view, at this time, buyer beware if you want a high-quality fitting with one of these designs!  At a minimum - know for SURE what the Loft and Face Angle settings are for the driver that you think you are able to hit well. 

 

Hot Off The Press - MyGolfSpy Driver Testing Results

There is a web site called MyGolfSpy that publishes some interesting testing results on golf equipment.  They have attempted to bite off a bit cookie - comparing driver performance results.  This weekend I learned that they would start sending out their results today - so why not provide these to you Hot Off The Press!

The first link is for a writeup noting the 17 drivers that were tested, shaft flexes used, and some preliminary information about the testing procedure:

     MyGolfSpy 2013 Driver Testing - The Contestants

The second link is to the results just made available today - rankings by what they call "Longest Driver:"

     MyGolfSpy Driver Testing - Longest Driver Results

There are a lot of ways to view these results - and until I can really understand the testing procedure used and evaluate if it makes sense, I will reserve judgement on if the results present any information truly of value in making decisions on choosing a driver for you.

Two comments now however I will say are justified:  a) with all of the variations in heads, shafts, lengths, shaft weights, etc. in the testing it is pretty amazing that there is only about 10 yards of variation in total driving distance as shown in the results; and b) the results are presented as though the Driver Head is King - but my first comment makes me wonder if that is a valid conclusion.

Still - worthwhile reading!  I hope you all go to their site and see the Accuracy results and Overall results that will be presented soon.  And I highly recommend subscribing to get MyGolfSpy messages delivered to your email.
 
Short Game Successes - Testimonial - And...

On April 13 we did an Edel Wedge Fitting/Demo Day at the Oak Ridge Country Club (thanks Jerry Williams!).  The most striking fitting results were for two low single-digit handicap players who went through the Edel Wedge Fitting.  Here are two quotes from them about playing 60 degree lob wedges in the past, and the Edel Wedge Grinds that gave them great results...

"I won't carry a 60 degree wedge in my bag, I can't hit it."  We fit him to the Edel 22 degree bounce DVR grind 60 degree wedge, and he was amazed at the performance.

"If I ever put a 60 degree wedge back in my bag I will quit golf."  Well, he hit every kind of conceivable wedge shot with an Edel 21 degree DGR grind - hope he is not serious about quitting!

High-bounce Edel wedge grinds can help players of all skill levels improve their short games!

We were delighted to get to work with Scott Moran, the Head Professional at the Fox Den Country Club in Knoxville, TN, on the SAM PuttLab.  Here is what he said about how this session helped his putting:

"I've known my negative putting tendencies but could not pinpoint the cause.  The SAM PuttLab pinpointed the source of my problem, and through practice I have all but eliminated my bad alignment."

Everyone who is tested on the SAM PuttLab learns information that can help them improve their putting!

Finally, Way To Go HARVEY GRAY, winner of the Challenge Cup from our yearly Florida Golf Trip.  The target is on your back for next year Harvey!
