6. To eliminate the steer it helps to eliminate straight line references, especially from the grip. As the putter swings and moves in the curved motion we still reference the flat portion of the grip to target. This conflict between perception – the straight line and actual path causes us to twist the putter as it moves along the path. The ball goes primarily where the face is pointed at impact as 82 % of the direction the ball leaves the putter is determined by face at impact. The twisting motion of the putter, as we try to match curved to straight, makes controlling the face of the putter much more difficult than if we simply allowed the putter to swing square to whatever direction the putter is moving during the stroke.
So by replacing the flat with a round reference on the grip we lose some of the urge to twist the putter while in motion. The “feel” reference of the straight line is gone and we are more likely to allow the putter to move freely with the path. Without the steer the results of the stroke become more predictable and our new found consistency makes us a better putter.
