I've been studying up on S&T; recently and took the few key points gleaned so far to the range yesterday. Have to say I noticed an immediate improvement in my ball striking and (particularly) turf interaction. Think I'm somewhat aided by the fact that I had very little lateral weight shift in my "regular" swing to begin with. From a range-of-motion perspective, as a tall guy the portion of the swing after contact seems to be the tough bit for me. I really have to think hard about left hip/left heel.
Thanks to all the participants in this thread. It is very useful to someone new to the philosophy.
Probably the wrong thread to pick for a first post, but yeah I use a 5 cent foam ear plug in my right ear whenever I'm hitting my driver in an enclosed range booth. As cited above, 110 decibels plus bonus slap echo is easily enough to cause hearing damage if you're practicing as much as you should be. :)
