Re: ShopTalk: Shaft Quality and Bend Profiles

[Ed Reeder]

My opinion is that the only factor of a shaft that influences head speed, other than length, is weight. Some people can swing a lighter shaft faster, while for others a heavier shaft can improve their swing mechanics/tempo and see a speed increase.  (For example, there is empirical evidence that backweighting increases some people's swing speeds). I can easily see how Flex can affect accuracy, but no way should it be able to increase swingspeed. The shaft is the transmission, NOT the engine.  Here is a simple test.  Lay an A-flex shaft and an S-flex shaft side-by-side on the ground.  Watch them for a few minutes and I'll bet neither one moves. /Ed Alan Brooks wrote: <snip>   In general, I believe the affect of the shaft on head speed is minimal, if at all.
