Not one book could see me shot and tell me what I was doing wrong. The dvd never once seen my elbow dropping. I had spent thousands of dollars on those books and videos and they never realy helped me get to the level of play that I desired.
We can learn a lot from books, DVDs, and great players, but without a solid foundation our progress is limited. Nothing will get you on the right track better and faster than a good instructor like Randy, Scott, or any of the SPF instructors around the country.
