Steve...That room looks exactly the same as it did last June, when I was giving another forum poster lessons there...and videotaping the lessons. The camera does draw attention from the other players, and a few came up to me afterwards asking about lessons. LOL
The first thing I noticed too, was the long bridge, which by itself, doesn't necessarily contribute to a less consistent stroke. However, your angle to the camera presented several opportunities to see that your forearm is also out of perpendicular at contact with the CB. It's very noticable when you are practice stroking, and your forearm is perpendicular, but the tip is a good 6" away from the CB. This contributes to missing the EXACT point of aim on the CB by tiny fractions. It also doesn't allow you a natural finish, where the tip should finish on or near the cloth, at the end of your stroke. One thing I would add to your set up, is a definite pause at the CB, before the last backswing and commitment stroke. I do like the fact that you're using the cuestick and timing for most of the speed in your game. Overall, I liked the way you play, but I'd tweak your pre-shot routine, to make it more consistent and repeatable. You have a nice game, especially for two years of serious play!
