If you have a lesson with a chronically back and in advanced skier who's very likely flummoxed as to why skiing steeper pitches takes so much energy, I like to work first on how to keep their feet under them and engage the ankle and feel where there feet are and what they're feeling... initially, the focus is fore/aft, then we work on lateral footwork and sensations allowing ourselves to move toward pressure and establishing platform angle. But as you know, progress is rarely perfectly linear, and often we need to get back to fore/aft when folks get back as their skis move into/toward the fall line. I do understand what you're saying though. Is it fair to ask you if you're viewing the issue within the higher level concept of milking the ski that you're currently playing with in your own skiing? If so, I'd say that milking assumes that a skier is well aware of, and in control of the relation of BoS and CoM.... you're proficient enough to play. Most skiers we coach, even very good ones, aren't quite ready for that. Some are, but that's generally a private lesson or divisional training group stuff.. and more competent racers of course. And I'm sure you have enough talented ski school staff at snowmass that this might be on the regular training menu for folks preparing for divisional staff or nat'l tryouts.... much more fundamental 5 land, that magic carpet that ties the whole room together.
