It's interesting that "slowing down the golf ball" is such a hot topic, yet to my knowledge, nobody on this thread has mentioned it yet......so.......I will.
And it really has nothing to do with professional golfers and accomplished amateurs reducing courses, particularly "classics", to pitch and putts.
It's probably because I play so seldom, and when I do it's certainly not in tournaments, and I don't give a shit what number I shoot, for the most part. Granted, it was pretty expensive playing balatas because I cut them all the time, but it was fun backing it up on the green, moving the ball on full shots and having no idea how far off line they would go on a violent missed hit. It was also fun to see how long you could play a balata, before it was rendered completely useless.
