Todd,
During the Epic gathering in Tahoe, the person you referred to conducted a 3 day seminar for those interested in improving skills. A friend who was in the clinic improved, greatly, over the 3 days. I skied with him the day prior to the class and could not believe how much he improved on the last day. I heard similar stories from another who took the clinic.
Regardless of school of technique, I will argue that the skill of an instructor to find the single largest improvement movements, and, how to communicate with the pupil to make the changes is of critical importance. Returning my golf analogy, a new coach has the option of working with the existing swing, or, breaking it down and starting anew. Even though my ski thinking may conflict with his teachings, I would pay to take the same clinic if I had the chance to do it over again. Feedback from a great set of eyes is precious. Yeah, maybe I'd translate some of what he told me into another system, but, I'd respect what he told me, and, see if it helped. In the same sense, if I skied again with Epic or Josh, and they were kind enough to offer some thoughts, I'm all ears.
