None of the above. If an intermediate has all or any of those technical issues I don't even think about teaching them to carve until they're addressed and overcome. Once that's done, teaching carving is a piece of cake, way less of a big deal than it's cracked up to be.
And I"m with Kook as to the virtues of teaching outside dominant initiations, and with Tog as far as the simultaneous thing being taken too far. Close works in more than horseshoes and hand-grenades. Ted's montage is proof of that in living color.
As long as the inside leg does not actually block the tipping, and finds a relatively similar edge angle near or shortly after initiation, that part of the equation is good to go. Unless you initiate bowlegged, or go through the turn bowlegged, or diverge the inside ski for initiation, then there's going to be some inside ski steering happening anyway, so all the contortions used in an attempt to avoid it seem like a lot of futile effort with little payback, all to strive for a arbitrary look. Thus why I'm glad to hear Tog suggest this trend is starting to fade. He
Hey Rick, thanks for contributing.
It has been my observation that, with many intermediates trying to break through to the next level, it is indeed the inside leg that is blocking the tipping. And this can happen for many reasons.
It is interesting that you don't see the inside ski playing a more important roll in the initiation "equation" and maybe this is where the two camps split. But I fully acknowledge that there are many ways to ski....I mean skin the proverbial cat.
