in a normal putting stroke the hands roll open then closed, in this one you should feel as the hands roll closed then open. The reason this was is the best is because having the ball of 1/2 inch on the position has no effect, on an open closed stroke it makes a big difference. I use this method and the way I feel about my putting is if I see the right line, my ball will go on it. Only way I should miss a putt is misread or bad speed, this method has taken line out of the equasion.
