Word. I don't believe it even removes the number of variables... the variables just change. That said, I don't like long putters and wouldn't use one. I don't actually care one way or the other about the rules change. It wont hurt my feelings at all one way or the other.The theory about making putting easier is impossible to prove. In short, it's a load of crap.
Thongchai Jaidee just lost the final of the World Match Play to GMac through poor putting - with his belly putter. He frittered away a 2 up lead by missing easy putts. All of a sudden GMac started sinking long putts with his short putter.
I'll stop before I get more started on this one.
