Mr. Bayley not sure if you noticed, but that was Mr. Jim Kennedy who you just quoted. However, I will answer your final question. I am presently 32 years old. I have competed with both golf balls. I picked up about one club of distance when I switched to a ProV, I have picked up another in the past 10 years because I am in better shape and stronger. I much preferred the old balls however because I could spin the ball and control it much better with the wedges, even with the deep box grooves from a couple of years ago. I can still work the ball however I want, its simple mechanics, if the club face comes through and strikes the ball facing left or right of target, the ball will go where the face is pointed.
Clubs and balls make less difference than you think, Mr. Bayley. The best players would still be the best even if the game were played with tobacco sticks and river rocks. And the worst would still be the worst. Bubba Watson and those guys would still be able to play out there, they have that kind of talent.
