This was on the Wishon forum . . . I thought I'd post it for y'all's benefit and reaction. Tom Wishon is one smart cookie. Blake and Wishon need to meet someday! He's really close to speaking our language with the stuff below. Can y'all say extension of the lever assemblies???
The benefit of a shorter driver and woods can all be substantiated by physics and can only be overcome by those few golfers who are blessed with a superior athletic ability.
It all revolves around MOI - in this case, the MOI of the whole club as it rotates around your spine in the swing and how the longer length can create enough of an increase in the load on a golfer to potentially cause breakdowns in the golfer's ability to repeat a swing move and swing consistently.
As you may know from reading here, MOI is equal to mass times the length squared. Therefore, the greater the length of the club, exponentially that longer length is really multiplied because length is a squared quotient in the MOI formula. So the longer the club, the more load the club is putting back on the golfer. And if the golfer does not have the inherent athletic ability or swing ability to be able to keep this load small from a higher MOI club, what can happen is a breakdown of the golfer's ability to keep the club on plane, on path and within the realm of proper/decent swing timing.
Granted, we are talking about the average golfer here, or rather in my off the cuff opinion, possibly 70-80% of the people who play golf. Here's the specifics - In a proper swing, we are taught to create a wrist-hinge angle (can't write the word wrist c**k because of the bad word filter on this forum software!) at the top of the backswing, and then to hold on to that angle as long as possible on the downswing before releasing it to hit the ball. The reason why this is a proper swing fundamental is because when you do this, the club and its headweight is CLOSER to the spine, i.e. the axis of rotation for the MOI of the whole club in the whole swing. So with the wrist hinge angle held intact during as much of the downswing as possible, the distance the club is away from the spine is shorter and there is less load on the golfer from the club, and the golfer will achieve a higher swing speed.
When you begin to unhinge the wrist-hinge angle, you start sending the head mass farther away from the spine of rotation - more LOAD on the body from the club in other words. And with avg golfers, this load can cause you to shift planes, shift swing path, and of course unhinge the wrist-hinge angle too early - all of which are BAD things in the swing. The longer the club to begin with, the more potential for this all to happen to break down the swing.
Even though the total weight of a shorter driver built to say, a D1 swingweight, is higher than a D1 driver at a longer length, remember that in the MOI formula mass is not a squared quotient as is the length. So the body can easily accept a little more mass but not so easily accept a longer length when it comes to the load brought back on to the golfer by the longer length. And the only thing that can counteract this is pure athletic ability of the golfer to inherently have the swing mechanics and coordination to adapt to the higher load of the longer length club. If you don't have that built into the swing/body, the physics of this says you are risking a breakdown of the swing.
Did a previous quote state that most Tour Players use a 1/2 inch shorter driver than standard length?
I believe that the Tour average length driver is 44.5". Traditionally, standard length was 43.5" in the era of steel shafts. Today, manufacterers seemed to have settled on ~45", but I don't think this has truly been designated as a "standard". However, most OEM products tend to fall between 45" and 46".

Distance is Magic; Precision is Practice.
Why not just build precision in the player to handle the longer shaft?
I liked the article and Wishon's company, but...Seriously, short for some. Long for others. There is no one size fits all.
I went to this old golf joint the other dude. . . old skool . . . and the old fart that ran the place had this piece of card board that he had put a matrix on . . . Loft Lies and Lengths from 3 different eras to current . . .
You'd have been surprised surprised surprised. The golf companies are mind-pimpin' us. You wouldn't need a gap wedge if you played with the clubs from back'n'da'day.
You should play the longest club you can CONTROL . . . I asked a question out here a long time ago about whether you'd rather have center face contact or more speed . . . HANDS DOWN HITTIN' IT FLUSH WON.
I think Eldrick was playing a 43 inch driver the year where he put everybody to shame . . . I bet most people play a driver that is too long for them and probably don't have enough loft.

This known as the Vanishing Loft Disease. Your brand new 5 iron has the same loft as the club they stamped with a #3 in the 60's and #4 in the 70's...Still think you need a 1 iron in your bag???
And they continue to do it as long as the consumer remains uninformed. Gotta make a buck.
The average length driver on the PGA Tour in 2004-2005 was 44.5 inches. The average club length sold to the average consumer is 45 inches. The average loft of driver on the PGA Tour at the 2006 AT&T Pebble Beach Pro-Am was 9.2 degrees, conversely their amateur counterparts had an average loft of 9.4 (the majority of which were over a 12 handicap).
I like shorter drivers, but I just don't agree the're for everyone. I watch Jeff Hull (he didn't know I was watching) give a driver fitting one day. The guy, a hack, ended up in like a 47" driver. I know Jeff knows more than me.
Some people control a longer shaft better than a shorter one. Why? Ask Jeff.
Watching Lynn's videos on the swivel and roll on plane was key to learning the #3. After improving my #3 accumulator roll (lots of repetitions it did not come easy!) the launch monitor indicated that more loft was needed. My left arm roll was now delofting the club but producing a nice draw. I am tickled that my average on a launch monitor is now 260 yds versus 230 yds one month ago. I hit a few over 270 - 278 being my longest. The driver is a Nike Sasquatch 13 degree with a stock 45" shaft. Thanks Lynn and LBG golf!!

Interesting . . . What did y'all do to your #3? What was the diagnosis and what was the cure?
You don't have that 2-piece-snack-box driver do you? That thing looks flickdid.
230 to 260 . . . I hope that lil' green b@st@rd gave you your money back.
