Im also a bit confused about the rotary movement..... some explanation would be nice.
I think these guys in the Oro Avanzato video are great skiers. Solid 10. They are possibly not Italian demo team members, they are probably just regular ski instructors that have been skiing since 3y olds and earning their living by teaching since 16y. There must be 10 thousands of those guys all over the Alps. Now they look 40 to me so they started with leather boots in the 60s, raced in the 70s with step turns, caught the first snowboard wave in the 80's and swapped to short carving skis in the 90's. When you consider all this the transaction they have made into new gear has been a great success for them. I have been skiing in the Alps since the 60's and no matter where I go, Italy, France, Austria, Swizerland or Germany those guys are for the most part unbelivably skillfull. Take in consideration that they are true all mountain skiers not one trick ponys like some of the new generation park or race skiers. There is absolutely no way anybody can get away by ranting on these guys skills. I could be wrong offcourse.
Up and down movement
I see some up and down movement in the video. I also see the same kind of up down movement in Grandis sking on the www.youcanski.com
site. This is part of a way of generate forward motion and building up pressure under your skis for better edge hold. Same motion as ice-scating backwards. It also makes it look dynamic. There is much less up and down movement in the GS turns. I think remarks on this issue probably refairs to other videos on the site.
I think their stand width varies a lot. Just like the guys in the WC when they ski SL. If its very steep they have a wide stance and if its flat and gates are set in a line they bring their skis if not completely together to at least a fists width apart. Varying the stance width like they do in this video I think is part of functional skiing.
At 0:29 we have some A-frame and at various other places as well. I dont think they actively even try to lose it completely. They ski bumps, powder, crudd and they have to wedge with students for extensive time periods. Only race coaches and carving experts rave about loosing the A-frame completely.
This is a great way to demonstrate carving. It has been arround for as long as I can remember and in the 70 this is the way we used to practise carving on those old straight planks. In the alps there are many times long flat transportation paths that were a perfect practising range for efficient edging. I use this as a demo for my students when we practise on our carving. Fun to see it in a video like this.
