Ray Martin's DVD
Ray Martin just covered beginner's stuff. I was hoping for him or someone else, to demonstrate the shots in his excellent book "The 99 critical shots in pool". If he would have covered this then it would have been excellent, but that did not happen.
There are plenty of beginner DVD's, and a lot of practice DVD's, what the market is really looking for is a good intermediate to advanced training DVD. Sadly, there isn't too much in this area
