Just my opinion...
As a 30 year league player (APA 7) I am asked for advice as to what books or DVDs to buy or what to do to get better, or what to do for a particular shot. (banks, draw etc.) So here is what happened: A lower level player ( APA 3) asked for help shooting bank shots. My reply: "I will help you with your stance and stroke because until you can shoot with a smooth repetitive stroke there is is no need to work on anything else. You are years away from needing to work on bank shots." The reply: "I already know how to shoot. No thanks."
My point: Books, DVDs and drills are fine ONCE you have proper stroke mechanics. Until then, you are only repeating bad form over and over.
