You make some interesting comments that bring a few things to mind. For one thing I doubt that there is a player on tour who does not or has not used some form of a Paul Bertholy drill. I see them all the time on TV and magazines. How many tour pros use Graves brothers drills and training devices?
As for mcirishman being confused I have thought that for years! You cannot argue with his success in improving his swing though. Do you really believe that your instruction is superior to Scott Hazledine's IMA or Golf Swing Construction 101 to the point that you can call a student of these confused? Or maybe you meant something else by what you said?
