new grips, new putters, blades, mallets, center shafted, different faces, milled and inserts,
different techniques, claw grip, left hand low, look at the ball, look at the cup, look at your thumb, watch the putter go back, ball in different positions in your stance
different lines, firm and to the center, die it into the cup from the pro side
I've tried everything but long putters and swinging left handed
