Sorry to take a few days to post back. Real life happens some times. Anyway, thanks so much for all the explanations. Going back and watching the videos again, I do see flexion of the outside leg at transition. And thanks for your analysis of the clips. It is really interesting/useful (at least I think it is) to see someone who is demonstrating good fundamentals skiing, then read a good analysis of their skiing, and go back and see if I can see the things in the analysis. Seeing things that are wrong is much easier when looking at video of someone who isn't very good. As things become more refined, it is harder to see the problems. (As in, with your skiing Geoffda clips here, my initial reaction was, "Right turns look good, but something looks a little off about the left turns. I can't quite tell what it is though.")
Anyway, here's to hoping that another camp or two this year will bring my skiing closer to this!
