Shafts are of differenct flexibities because golfers swings vary widely from player to player. Swingers, hitters, throwers, late hitters, slow swings, fast swings, different loading points and amounts all make for variations requiring more or less flex. From what I can gather, quality in a shaft is mesured by how similar individual shafts of the same grade/type are. -- bill-o A "gimme" can best be defined as an agreement between two golfers neither of whom can putt very well.

Jack was a great golfer, but I don't think he was a great theoretical thinker about the golf swing. He made several errors in his books. But the telephone pole thing was something he actually experienced, not some theory he had.

How is it not an indication of quality? Why do they require different shaft flex? So a very crappy shaft model if it's made very precisely all the time it's a high quality shaft? The quality of a tool is determined primarily by its ability to perform the function for which it was designed and built. The better it can perform its function, the higher its quality. The worse it can perform its function, the lower its quality. What is the function of a golf club shaft? Can a rigid lever transmit the same power more precisely than a supple lever? Is a golf club shaft a lever? Martin Levac
