Just wondering if you think that Average Joe golfer (i.e. me)would get much value out of, what appears to be, a pretty technical book like The Golfing Machine? I'd like to think that I'm a pretty bright guy but I don't want to shell out for a book that might not be of much use to me. I know that I would really like to be able to follow some of the discussion threads that contain "extensor action" and "10-k-4"'s. Any thoughts from you non instructors out there who have (or haven't) valued the instruction contained within?
