And while that may be true, it does not mean the concept is right for every golfer. If it was, more people would be using it and less would have abandoned it so quickly. As I said, as we have spoken to more and more golfers of higher abilities they share similar thoughts.
Are you stating the laws of geometry, physics and calculus vary from person to person? You state that various people leave the S&T group, where is Weir now? Weir won millions using S&T, yet what has he won since? Badds was 20th in the world with S&T, and is now 51st, even after a recent win after being away from Mike and Andy for a few years. That's the actual beauty of Stack and Tilt, people say there is no swing theory that is right for everyone. That is simply not right. Explain to me how your experience is in anyway a fair test of the Stack and Tilt system. Did you ever have a lesson with an authorized Stack and Tilt instructor? I don't think I've heard of one person getting a lesson with a S&T instructor and walking away unsatisfied. Do you think watching Kobe Bryant's instructional videos will make you able to hit a turn around 25 footer? Or would a lesson with Kobe help more? It's rather foolish to bash stack and tilt as you do, when you did so little to even see if it would work.
It's a swing that is different than the swing you have most likely been using for years. You have all your bad habits engrained, and you think that is magically going to be fixed by watching a book or reading some DVDs? Show me a player that got worse with S&T, after giving a full and honest effort, then maybe your points have some merit.
Edit: I'd also like to point out that it is essentially the S&T guys that made it common knowledge that path controls curve and face controls starting direction, meanwhile your standard instructors(think leadbetter, Haney, Harmon) all say still that face controls curve. So which do you believe?
