I think you and he are in a position to agree to disagree.Hm. Okay, yeah. I took your statement to mean that anything other than carving is "less than," and that I disagree with. I do agree that heel pushing is suboptimal (as I said, there are particular snow conditions in which it's a real problem).
I think anything that isn't a clean carve is inefficient, which means you're using more energy than necessary and more torque on hips, knees, ankles, etc.
But some terrain requires an inefficient approach to be skied efficiently.
Skiing steeps, chutes, moguls, etc *can* require something different than clean efficient moves.
