I am not sure that this is the place to say this, but I want to second Yoda's comment on laser plane-line-tracing aid. This past Christmas I received one as a gift. It was the kind one attaches to the shaft. Unfortunately, I could never get on plane with it. My right forearm did not point inside the plane line, but outside it. And it caused all sorts of grief. On the course, I was constantly searching for the correct plane and ended up most of the time on a severly flat plane, well below the TSP. That made it extremely difficult for me to hit the ball first with any kind of power. I finally junked the laser aid and went back to the dowels Yoda gave me last year. It was a revelation, and every thing is back like it is supposed to be. In my case, modern technology did not help.
