I'm continually impressed by the material and its presentation, Bob and Dr. Dave. It's amazing what can be done at home with the right equipment in the right hands (and a lot of work!).
dr_dave... thanks for the post on draw... I learned a lot I didn't know and reinforced what I did from your clear explanations and slow-motion photography. Your knowledge and dedication are greatly appreciated. Your web site is bookmarked and your book "The Illustrated Principles of Pool and Billiards" is a dog-eared reference in my library.
It's actually been helpful to me also. After filming and editing the videos, my draw seems to be more effortless and under better control than normal. It obviously helps to keep reminding the brain about the important fundamentals. (It also helps to practice.) Keeping the grip relaxed and the elbow still into the ball is critical to a good draw shot.
