I just played in a Pro-Am today and shot a 6-under par 66. I felt really good and thought I had won. In the tradition of celebration and because it was so damn hot I was getting a cold beer when a friend of mine said he was buying. I told him there was no reason to buy but he said that the time I spent with him on the range before the round cleared the fog and he had great motion all day. He could not believe how solid he hit the ball compared with how he was hitting it.
Well the beer was a cheap price for the lesson considering he shot 65 to clip me by one shot. Oh well, I felt really good I was able to help a fellow pro play well, even if it meant beating me.
Moral of the story is that there may not be a good reason to change your motion, especially if you already hit it good. Stay with the alignments and produce YOUR best motion. Beauty is in the shot, not the camera.
