USGA and R&A ban anchored strokes. PGA of America was in support of anchored putting.

Hell, I'm just a hacker that has played a good bit.
I've about quit.
I'll say that most of the regular groups that play with or have played with, are pretty strict on the rules.
Generally speaking if USGA makes a change we abide by it (equipment wise anyway).
In this case the club is still ok, but not how it could be used.
I still love the game.
I'm surprised they didn't grandfather them like they did the Ping Eye 2s with square grooves.
