As far as judging his skiing-hey, you've been working hard on good skiing (lessons, camps, practice, skiing, etc) for some years, I'd gather--you're probably as good as anyone to know what looks good. After all, you don't have to be Wolfgang Puck to appreciate a good meal
Pardon an anecdotal story. Years ago, I was on a ski vacation with a trained chef who cooked each night. Throughout his cooking, he would invite us to taste, and, then ask "what does it need to get better". Then, he would explain the aspects of "tasting" skills, add whatever and on retaste, it was much better. So, Liam, I can appreciate great food, I just can't ,make it!
So, in doing MA about skiing, it should be about finding movements that make us better. It been said of HH that he is a "demonstration" skier in that he's defined an effective technique and specific language, then, goes out and skis it on every turn. That's not a flawed teaching process, it's talking the talk...walking the talk. PMTS may not fit all types of skiing in all situations, but, it does put up a standard, complete system. I don't know jack about CSIA level 4 skiing.
In my head, I try to take all the points made about his skiing, subtract the negative, and then try to figure out if they apply. An aspect that I totally agree with BW about is that no one knows the specific intent of what the skier was trying to do. My guess here is that he is trying to do some solid, visually attractive skiing to entice people to come to his camps and improve to his levels. "This ain't no Steep and Deep" skiing! Like Liam, I find this good, real world, expert skiing on an in-bounds mountain. I'd love to ski with (or way behind) this guy.
It's interesting that there is a little consenus that he could by more on edge and carving before the fall line, and, BW pick-up on some counter acting.
@ Bush, have you ever skied with Helluvaskier? I know that your values for where and how you ski are much different, but he's one PMTS skier I'd put out there who rocks down a hill!
