It's kinda cartoonish in some places and the author is obviously controversial, but you'd do whatever this guy says if you saw how he dominated in '00 - '01 (See '00 U.S. Open highlights at PebbleBeach). This book is very fundamentally sound. I genuinely think that anyone can get to a 5 handicap by following these fundamentals. It covers all aspects of the swing and game. I feel that my game took the biggest leap forward after reading this.
