While studying the different effects of loft on a putter, Michael Breed (you know, the real hyper guy on the golf channel), came upon the fact that the same putt can have different amounts of break, not just due to speed, but also due to impact! 2 guys could hit the ball the same distance (let’s say 20 feet) on the exact same line, and they may break differently due to the loft of the putter at the moment of impact… More loft, less break. Hmmm….
Probably won’t help your game, but I thought that was a fascinating fact. Enjoy your day.
