And, the golf ball won't go any farther.
Unless, you consider that Mickelson declared that he gained an additional 15-20 yards by going to a 47 inch shaft.
Vijay Singh and Davis Love have also experimented with 47 inch drivers.
Presently, accuracy is a trade off problem, but, it's only a matter of time before the hi-techies solve that problem.
The USGA shaft length limit is 48 inches.
20 years ago the standard length of a PGA Tour Player's driver was 42.5 inches.
If shaft length was limited to 43 inches, head size to approximately 250 cc and COR regulated, then only one issue would remain...... the ball.
If there isn't a retro spec, the ball's going to keep going farther and farther.
Average PGA driving distance in 2005 = 288.9
22 % averaged more than 300 yards.
Nicklaus at his best couldn't average either of those numbers for the season.
It's time to support the USGA and their efforts at dialing back the specs for I & B.
