Good luck in your match. Id keep your mind on your motion or pressure points and forget all of this stuff till your done.
But in my last lesson with Lynn, the aiming point for me anyways moved around. More target ward or in front of the ball for a wedge say and behind the ball, rearward for a driver. Its all about the length of the lever that needs to switch ends. If I start leaving my drives to the right I adjust my aiming point and look at it instead of the ball, like one would do in a bunker. Et viola, thank you Lynn.
