Which Driver Shaft Length?

When I tested my old college driver a few weeks ago my interest was piqued by how close my swing speed with the 43.5 inch club was to my current 45 inch driver. I have heard that altering the shaft length of your driver by an inch can/should alter the club speed by up to 4 mph. This called for a test.....

Using TrackMan my idea was to test the same golfer, clubhead and golf ball, but change the shaft length. I took my current driver, which is the Titleist D3 8.5 degree (B1) with a 45" Motore F3 70 gram stiff shaft and tested it alongside the same head (B1) with a 43" Project X 82 gram stiff shaft. Essentially a driver shaft versus a 3 wood shaft. I had recently came across a 42.5" well kept old Wilson Staff JP persimmon driver with a steel shaft and decided to include that in the testing.

I hit 11 shots with each club and eliminated the data for the poorest shot with each club. I was using fresh Titleist NXT Tour golf balls and it was a perfect 80 degree day with little wind. The results were astounding!

With all three clubs my tendency was to hit up on the ball with a slight in to out club path. My swing plane was very consistent from shot to shot (which surprised me a little actually) and the clubface was almost always slightly open at impact. This path and face relationship led to an average shot shape of a slight draw. Here are the numbers:

45" Driver Shaft

  • Club Speed 101.3 mph
  • Ball Speed 151.6 mph
  • Spin Rate 2697 rpm
  • Launch Angle 11.3 degrees
  • Carry 245 yards
  • Total 272.2 yards
  • Height 76 feet

43" Three Wood Shaft

  • Club Speed 101.1 mph
  • Ball Speed 150.0 mph
  • Spin Rate 2100 rpm
  • Launch Angle 14.0 degrees
  • Carry 249 yards
  • Total 278.7 yards
  • Height 84.3 feet

42.5" Persimmon Driver with Steel Shaft

  • Club Speed 93.4 mph
  • Ball Speed 141.2 mph
  • Spin Rate 2115 rpm
  • Launch Angle 10.3 degrees
  • Carry 206.4 yards
  • Total 246.4 yards
  • Height 48 feet

I couldn't believe it! I hit my driver with a 3 wood shaft further, higher, with less spin and above all else - straighter. Take a look at how much straighter: (yellow - driver shaft/purple - 3 wood shaft/ white - persimmon)

I also totaled the distance (after roll) the ten shots with each club finished from the center line:

  • Persimmon - 182 feet (average 18" off line)
  • Three wood shaft - 234 feet (average 23" feet off line)
  • Driver shaft - 315 feet (average 31" off line)

On my Andrew Rice Golf Facebook page I asked readers if they had any experience with shortening the shaft of their driver and here are a few of their responses:

"I just went to a 44" and am loving it! Longer then my 45.5" and straighter too!" GT

"Went to 44" and more consistent with no loss in distance" AvS

"44" Callaway...more fairways AND more distance!!!" CL

"Went to 44" and I hit it more solid further and straighter" PW

"44" this year. I agree it is far better. Middle of the face more often." SF

"I found it made me less steep through attack so I have lowered my spin rate and launched it about a degree higher" AB

By the way - most of the above quotes are from full-time professional golf instructors. So what can we learn from this research?

Having tested a few golfers with shorter shafts it seems to me that each golfer has a 'threshold' length - an ideal length that gives them the optimal combination of speed and accuracy. For some that threshold could be 46"  while for others they perform best with a 42" driver. The only way to find out is to get yourself with a teacher or fitter that has access to Trackman and various shafts.

Another point to note is that while the 3 wood shaft had a slightly slower club and ball speed the shots were longer...why? Notice how the launch angle was higher while the spin rate was lower. A perfect illustration of the term 'high launch low spin'. Launch the ball higher to get more out of your tee shots.

What can we learn from the 'persimmon' data? While that shaft was even shorter than the 3 wood shaft it was substantially heavier. I believe the 3 wood graphite shaft was almost 50 grams lighter than it's steel counterpart which would explain the almost 7 mph difference in club speed. The size, or lack there of, of the head was intimidating in the beginning, but as I went through the shots I became more comfortable. I believe that practicing with a smaller clubhead like this can only be beneficial in the long term for any serious golfer.

My feeling standing over the shorter club was better and almost every golfer I tested reported the same sense. The club feels easier to control and many golfers have reported a feel that they can 'get through' the shot better. I really felt like I could smash it without it going off line - a nice feeling!

Physics says that longer shaft + lighter shaft = faster club speed = more distance. On paper that might be true, but when the human element is involved everything changes. The next time I tee it up it will be with a substantially shorter shaft in my driver...but that's just me!

Spin Rate and the Driver

I was recently teaching an accomplished senior golf professional and he happened to hit three very interesting consecutive shots. They are illustrated in the image above starting from the orange circle and working up to the blue circle.

I thought there was some valuable information to learn from each of these three shots. Here is some TrackMan data to ponder:

Orange Strike

Spin Rate - 3252 Launch Angle - 7.5 Total Distance - 256.5 Club Speed - 103.6

Green Strike

Spin Rate - 2623 Launch Angle - 9.6 Total Distance - 269.5 Club Speed - 102.9

Blue Strike

Spin Rate - 1928 Launch Angle - 10.9 Total Distance - 274.6 Club Speed - 103.1

My experience has shown that golfers tend to be fairly consistent when it comes to club speed and this illustration shows us just that - there was a change of less than 1 mph between the golfers slowest and fastest swings. Nothing new there...

What is interesting is that where the ball was struck on the face, influenced the spin, launch and ultimately the distance that the shot traveled. You may have heard that with a driver you want to launch the ball high and spin it low. The purpose of this article is to get you to start believing it! 

Stay tuned as this is the stuff that can make a tangible difference in your game...

Launch Angle

The clubface is curved from top to bottom and this is called roll. If you have a 9.5 degree driver that means (assuming the manufacturer is correct) that your club has 9.5 degrees of loft in the center (picture the "equator") of the clubface. If you strike the ball lower on the face your club effectively has less loft and vice versa for a higher strike point. well hitting the ball higher on the clubface introduces more loft to the ball and it will thus launch higher - bingo! We've got the higher launch taken care of. As you can see the ball launched more than 3 degrees higher by elevating the strike point.

Spin Rate

But what about the spin rate? How do you get that down and what is ideal? I have great news, as this is a two for one deal. When you strike the ball higher on the face the "off-center" hit causes the clubhead to twist slightly during impact and this leads to vertical gear effect and a strike above the equator will have less spin than a strike below it. I prefer to see a spin rate somewhere between 1900 and 2400 rpm's if you're looking to really make the ball go. It's amazing what a strike point that's about 1/2" above the equator will do towards getting you into that optimal spin rate range.

If you're wondering where to strike the ball on the face the above photo is just about perfect - a touch above center for higher launch and less spin and a touch towards the toe for a hint of gear effect draw. Who wouldn't want to hit high launching, low spinning, baby draws that go 20 yards longer with the exact same club speed?

Centeredness of Contact

As you may have heard, it's all about impact! And it really is. The most important part of the golf swing is the point at which the golf club communicates to the golf ball - impact. The ball spends 1/2000 of a second on the face and it's during this sliver of time that the outcome of every shot is determined.

I often share with golfers how the laws of physics cause the ball to respond to the club, and while this information is helpful it refers primarily to centered hits. It is too seldom that I discuss off-center hits and how the ball responds to this frequent occurrence. Today's the day!
When the ball is struck anywhere other than the center of the face a phenomenon called gear effect occurs. Ever heard of it? It causes the ball to draw (or fade less) on toe oriented hits and fade (or draw less) on heel oriented hits. I often see a golfer struggling to stop the ball from fading, yet every shot is struck off the heel or inside of the face. Gear effect is elevated when you use clubs with larger heads such as a driver and it's actually the reason why the face of a driver is curved from toe to heel and from top to bottom. The curve on the face of a driver actually gets the ball, when struck off the toe for example, to launch to the right (for right-handers) and then gear effect causes the shot to curve back to the target. Gear effect plays a role in all shots where the ball is not struck in the center of the face and let's be honest - and that is most shots.
The research I have conducted using TrackMan has shown that better golfers (single figure handicaps or better) hit the sweet spot or center of gravity less than 20% of the time! Think about that for a second...
The best method to ascertain where you are striking the ball on the clubface is to use a dry erase marker to cover a portion of the face. Hit a shot or two, take note of where the strike occurs and then re-apply. After a handful of shots you'll start to get a good idea as to what your tendencies might be because, while you may not hit the sweet spot often enough, most golfers are fairly consistent with where they miss.

Keep in mind that it is very difficult to influence where the ball is being struck on the face by altering your distance from the ball. For example, heel hits do not mean that you should move away from the ball as this will more than likely cause you to reach out for the ball even more and exacerbate the problem.
Once you start to learn what your tendencies are an excellent drill is to position a row of tees just outside the toe if you hit shots predominantly off the heel and vice versa for toe hits.
After a few shot you will start to sense what the body and arms need to do in order to make a quality strike in the center of the clubface. Give it a try!

Thanks for reading and good striking!

Golf Has Only Nine Shots!

I've got all the shots I'm just not sure when I'm going to hit them!

Control Your Ball!

Or what about a shank, a top, a blade, a whiff?  Okay, there are only nine proper shots that a golfer needs to master.  They are the low draw, straight one and fade; the regular height draw, straight one and fade and the high version of each option.  Tiger Woods incorporates all of the above shots into his practice sessions - shouldn't you?

Try this fun and challenging exercise in your next practice session:

  • Be sure to use an alignment string that is set up to a target within range of a 7 iron.
  • Keep the size and pace of your swing at around 75%.
  • Start on the 'ground' floor (low) with the shot shape that is most comfortable for you (draw or fade)
  • Stick with the low shots until you have hit one of each.  Keep in mind the draws/fades should start at the target and curve away from it.
  • Work up to the medium and high trajectory shots until you have also hit one of each.
  • Keep track of the number shots required to complete the SLAM (all nine shots) and set yourself a target score for the next time you practice.  The fewer shots, the better.

This exercise will illustrate to you the type of shot that is most difficult for you to hit. (Hey, some golfers just don't know!)  Practice the most difficult shot until you can pull it off on the course.  This will serve to neutralize your swing and allow you to ultimately hit the ball straighter.

If you struggle with slicing the ball, practice hooking the ball!  If you hit the ball inordinately high, practice hitting low punch shots all day long until you can hit it at a regular trajectory.  Get to a point where your extreme misses are less extreme than before and the ball will stay closer to the intended target and your scores will do the same!

Over the upcoming week I'll address the techniques required to hit the ball low or high and with a draw or fade.  Check back!

Things to Ponder:

  • At the Texas Open this Lance Ten Broeck, both caddied for Jesper Parnevik and played in the event. They both missed the cut but what must it feel like as a player when your caddie beats you! (Ten Broeck 141 vs. Parnevik 144)
  • The PGA Tour must be struggling to find players.  I can think of 20 golfers better than a caddie and a dozen washed up golfers from the 80's to play in a PGA Tour event!
  • And this little interesting snippet from www.geoffshackelford.com

John Huggan with this nugget from last week's Players:

Not only did the diminutive leader of the world's richest circuit manage to mangle the champion's name, calling him "Heinrik" more than once, Finchem's minions were apparently hard at work pressuring host broadcaster NBC into not mentioning just how many Fed-Ex Cup points the Swede picked up along with the $1.7million first place cheque. Embarrassingly, that number is nil, due to the fact that Stenson (who will no doubt have welcomed the sizeable boost to his bank balance in the wake of losing a goodly chunk of his fortune amidst the recent Stanford fiasco) thinks he can muddle by without being a PGA Tour member.

  • Don't think the PGA Tour does not go out of their way to censor what information we get during the broadcast of their beloved 5th major!
  • Zach Johnson is quietly becoming a top five player in the world.  Gutsy!

Prevalence Under Pressure!

Cabrera and Co.Congratulations to Angel Cabrera on winning the Masters and his second major. It's true what they say about the Masters, "It all comes down to the back nine!"  The difference this year was that it all came down to the final two holes. Seventeen and eighteen favor a straight or left to right ball flight and I believe that really made all the difference in the outcome. The major players were Cabrera, Perry, Campbell and Mickelson. Cabrera was fading the ball comfortably all day, Perry and Campbell are known drawers of the ball and Lefty had his fade working. Mickelson attempted three draws on the back nine, all with poor results - tee ball @ 11 (trees), tee ball @ 12 (water) and tee ball @ 18 (bunker). Every other tee shot on the back nine played into his fade perfectly.

Perry and Campbell started to come unglued down the stretch with typical mistakes that drawers of the ball make - blocks and hooks.  They both hit a few of each and it was clear that the recent constriction of 17 and the fade required off 18 did not fit their eye. Now, they both hit the 18th fairway in the playoff, but the doubts raised by their earlier mis-steps remained and eventually proved to be their undoing.

Cabrera was a different story. His fade seemed to hold up when he needed it most (18 in regulation and the second at 10) and with a few saving par putts he was able to keep himself in the game. What a beautiful shot he hit into 10 for his second!

Here are a few points that caught my eye during yesterday's broadcast:

  • A fade holds up better under pressure as there is less timing required
  • There is no such thing as a perfect swing, only a functional one
  • Never give up! No matter how many trees your ball hits you are never out of a hole
  • Once the Tiger and Phil show ended it was nice to watch the Masters
  • I like Billy Payne - I think he will do a great job for Augusta National
  • Phil is now officially longer than Tiger (even when he fades it!)
  • Tiger curses on live television more than anyone I have ever seen!
  • I would like to play Augusta National every day!

Remember this - draws go further, but require more timing and are thus less consistent. Fades finish straighter, require less timing and are thus more consistent! Every good golfer I have ever taught is seeking consistency.
