In a brushed carve, the tail of the ski follows the tip with some displacement. Since the tip is tracing the arc and the tail is brushing, is it even physically possible to start a brushed carve with no tip pressure on the ski?
I've observed that when I'm practicing edge-locked carves, if forced, I can start the next turn from the backseat and I'm usually ok as long as I can pull my feet back enough in the next transition; the ski can still arc. Brushed carves, different story. When I try to start a brushed carve from the backseat, the arc just completely collapses; the tips catch the snow and the tails break away. Worst of all, when it happens, it screws with my balance so much that all my following turns are garbage.
An example of this is the video that I just posted in my MA thread (https://youtu.be/ryEEU6Wcg-c). It starts on my 9th turn (9seconds). I don't know if the turns before that are technically sound, but I can at least say that the tails are following the tips and the stance ski isn't getting pushed around by the crud. The second I got lazy with my foot pullback, everything including the rest of my turns were spoiled. I have difficulty adjusting my fore-aft when the pitch changes; around the 9 second mark the hill starts to flatten out.
So, theoretically, is it even physically possible to start a brushed carve from the backseat (not that anyone should)? Is that one of the reasons why its so elusive?
