The balance thing has kind of always bothered me. (Disclaimer: I've never been called or warned for a foot fault). For instance; if the same rules were applied to NBA; we would have never gone beyond the set shot. Probably few on here who even remember basketball when player's shot from a set stance. Of course, your body moves forward when you do an athletic movement. For some of us (read me) this issue has been in our heads while putting, for years. Just how much "showing of balance" is required? I say at least a full 30 seconds worth (of course not so much that the time limit "for speed of play is violated)!! All players from now on must extremely sophisticated motion detectors to note absolute proof of balance; and stop watches; to determine speed of play issues.
