My observation is that knee stress from tipping wider skis can be a good biofeedback indicator of incorrect tipping movements. If I tip my skis through knee angulation (driving the knees toward the inside of the turn) then I have pain on wider skis. Instead we should be keeping the stance leg passive and tipping the inside free foot when it's light. This keeps the stance leg "stacked" and greatly reduces the stress on that knee.
I agree HA.
I'm thinking that the moment of greatest stress on the joint will be when I transfer to LTE with the knee fully flexed on piste. I am hoping that this will be a much lower momentary stress than what I am feeling on the incline board, ( ie ms rather than seconds) It won't be the free foot that is the issue, but the new stance foot, so tipping the wider ski, although technically more difficult shouldn't be an issue for my rehabilitating quads which are still a little weak (but improving by the day) extending from a fully flexed position.
Regarding advice on stopping in steep chop, it appears that no one knows or is willing to share. It's a shame really. As I'm sure there are a lot of lurkers that could learn from any advice given. Me? I'm just going to "go for it!" flex deeply and trust the moves.
We'll know soon how that works out.
