This really is a great photo sequence of some steep corn snow turns. And, wow, 5 pages of discussion. Well, four anyway. Not that I read every word but there is some good stuff for sure. And just because it's still going, I thought I would add a few comments.
It looks to me like this is a good skier in good snow, good pitch and maybe a bit of weight in his pack. Overall he is linking some pretty nice, solid short to medium radius turns appropriate for the terrain and snow condtions.
I also believe that all of us have things to work on to improve and evolve! So, I would offer that the biggest issue that I see, the first thing I would have him address, is right at the critical moment of setting the edge to finish the turn and the movement coming out of this set of the edge(s).
IMHO, he looks too far forward at the end or edge set of his turns. Look at photos 19 and 22 & 23. You can see this by the position of hips relaitve to his hips; they are tucked too far back and he is crushing the front of his poor boots.
This concentrates too much pressure on the front of his skis. So, the skis (or ski) will buckle, punch into the snow or hesitate for a moment and he is popped clumsily towards the new turn. He looks awkward for a moment in photos 19, 20, 42, 43 because his legs, particularly his downhill leg, are not in position to most effiently release the turn, control the kick because of the buckle and start the movement of the feet into the new turn. There are some photos missing in this critcal, in my opinion, part of the transition between turns, for example between photos 22 and 23.
He definately gets back over his skis,though, as he comes into the top of his turns as shown in photos 35-38. I'd say his stance is right on at the top of all his turns. The most suspect in this regard are photos 29 and 30, but by the time he comes into 31 - 33 he is right over 'em again. I think he is more likely handling or compensating for the weight of his pack. But who knows for sure, he could have stuffed it full of paper bags to look cool for the photos.
So, overall, I think he may not be the prettiest skier, but he can handle this pitch well. From these photos I would say that his skiing through these 8 or nine turns (a fair number to get a feeling for his skiing) that he would be consistent with a Level 9 rating.
I would be curious to see him ski the same pitch with the same turns in softer, deeper or more variable snow. In these snow conditions, his hard forward pressure on his skis and boots may present more trouble for him then is presented in this sequence on buff corn snow. The firmer, glory corn snow is solid enough to support the concentration of forces on the ski front and make it much easier to link turns.
So, that's it for now....just thought I'd throw another bone at this dog that just won't quit!!
I hope everyone is getting a few turns in,
Cheers to all,
PS sorry about any blatant ttpyos. No spell checker, don;t ya know.
