In less than 3 months I re worked my whole game after many years by using Mark Wilson's book. I tightened my bridge, loosened my grip a lot, changed to Mark's PSR (more or less), am keeping my eyes on the OB a lot more than I did and have a softer, smoother, and straighter stroke . After I had the loose grip down I had some problems getting too short or too long on position, but little by little that feel came around. I can't thank Mark enough for publishing his book. There is just something about the way he writes that I got right away. Now the rare times when I miss a ball I stand there in shock like I'm Mika LOL. JT
