SkiDude, I agree his skiing is high level and I agree with RicB, at any level there can be coaching. You think the WC coaches sit around all day and only tell their skiers how great they look? I certainly hope their only advice is not to tell the skiers to go faster through bigger bumps. I would hope that they would analyze the deficiencies and then in fact take them back to "tamer" terrain to focus on the specific movements which are not as effective as they could be. Taking it up to nastier terrain later goes without saying.
This is where Viking needs to go.....sure he may need to further refine his core technique, or fundamentals...but exactley where that effort needs to go, could only be determined for sure, by seeing him push the limits of the technique he has now....I wouldn't cheat a student of this calibre by "assuming" where he will fall apart when he dials it up.....I'd try it and see...and if done right, it should be FUN and INSPIRE the student to new hieghts....and just before the safety police jump in...there is no reason why it can't be done safely as well.
Going back to "tamer terrain" would bore this guy to death...talk about missed opportunity!!...skiing should be fun, and lessons should be awesome...and working on simutaneous edge changes or longer legs is all dogma until you actually see these things holding him back....
