So for those of you advocating a wide range of ankle action in the fore-aft direction with ankles opening and closing, under what circumstances do you choose to pressure the back of the cuff, and for what benefit? This is certainly a part of maximum ankle movement in the fore-aft plane. Are your skis weighted when you pressure the back of the cuff with open ankles? How is this beneficial? Do you do it at end of the turn so the tails grip?
Or do you choose to only go back as far as in the middle of the cuff, not allowing those ankles to open up completely but stopping them when the lower legs get to the middle of the cuff? Is this the tension you maintain?
And when the ankles are open to the extent of having the lower legs come up perpendicular to the skis, and your lower legs are upright on the skis instead of tilted forward as in those images I just posted, and your tongue-shin pressure is low, what part of a turn is that and what's the benefit? Are the skis weighted at this point? If they are weighted, and you aren't aft, you must be bent forward at the hips and the knees must be open. Like using a walker. I suspect this is not what you are advocating. Maybe there's another way of staying off the tails when you have upright shins and/or are pressing against the back of the cuffs.
Or is being aft as you open your ankles with shins getting upright on the skis just fine because at that part of the turn you are light or floating? (This I understand and am familiar with re: reaching short radius turns, top part of turn, as skis reach out away from the skier.)
Or when your shins are upright, are you in the bumps skiing a direct line, flexing and absorbing and back-pedaling like mad? I do know that Bob Barnes' graphic of back-pedalling does not show ankles opening and closing; they stay flexed and stable; their shin-tongue pressure is maintained with tilted forward lower legs.
