I don't have any statistics other than the fact that I won 10 club championships with short putters and only one since I switched to the long one, which by the way I remind you again I use in the "approved" method.
This quote also reveals the disdain out there for long putters, by your not considering them "real." The revisions say the long putter is as "legal," or "real" if you prefer, as a short one. It is the "stroke" that is supposedly in question, although it is really not.
What this really is about is that a majority of the old guys think like you, don't like the looks of long putters, and don't think they are "real." They didn't putt that way and they believe it is their holy duty to uphold the integrity of the game.
The integrity of the game is just fine, old guys. Butt out.
