Most people are not doing this, so I think the ankle open stuff is not so applicable in normal skiing, shortish turns.
Nailbender, I specifically said dynamic medium radius turns and will add - on blue black groomed terrain, of moderate to high speed at a turn radius shorter than the sidecut of the ski with minimal skidding for those into "it depends". I do not want to get into short radius turns and certainly not your QCT's.
I saw the specification for med radius turns, but mistakenly thought you had previously commented what LiquidFeet wrote.
Hopefully the post will help those looking for insight into skiing any natural terrain more dynamically and confidently, obviously you've got this spectrum of turns dialed in.
