i consider myself a good putter, but i'm curious enough to try it on the next practice green i am on. cool stuff, thanks and for anyone who cares, i became a good putter by doing 2 things, every single time. First, for any putt outside of my peripheral vision when i am looking at the ball, i pick out a spot or 2 on the green about 2 feet away from my ball that i want to roll the ball over. once i see what that target is, i no longer need to worry about when i am aiming. i can solely concentrate on the distance. 3 or 5 continuous practice strokes while i am figuring out how hard to hit the ball and i'm ready to go. then step up, find my target spot(s) on the green, and putt away.
