On maintaining your heelside edge on steeper terrain, look across the traverse and stay aligned. Fight the temptation to look down hill. And get lower and flexy knees. That should help. I don't think it's your binding angles; ride what's comfortable for you.
Yeah you might be hunching because of the camera. Have a buddy record you and see if you still do it.
Crossunder is a more powerful and efficient turn initiation move because you start the turn low and in more power and control, and rise through the turn, thereby pressing the edge throughout the turn. Crossover you start tall at the top of the turn and have to drop down to pressure the edge. It's an extra move.
Yea, I constantly remind myself to not fight the turn with the upper body (corkscrew on toeside and just facing downhill on heelside)... sometimes I get it, sometimes i just give in and square myself too much. Normally when I fall its only that: washing out, and hardly ever toeside. And yea, the binding angles are really comfortable... I don't really want to change them.
I have done that run several more times without falling at all, but when I square up and fall in the video is how I would normally fall.
That blue run should be straight up on edge, no skidded turns unless you need one just for burning speed. Engage the edge and stop the excess turns, especially when no one is around like in your video.
On the steeper run, your having a similar problem when your washing out.... Engage that edge and don't unweight it so much/so long to prevent washing out.
I also agree with watching your line, not the bottom of the run or the rest of the mountain....
I'm no pro but it is a rare thing for me to be on my ass or knees. I keep the edge engaged until right when I want to turn..... When you get into gnarly steep terrain it is supper dangerous to wash out since self arrest can be difficult in some situations.
So the goal should more or less be no skidded turns at all?
yikes that'll be fast. I ussually bleed some speed off... but on a day like that one, I know I should have let it rip because the snow was very consistent and not too much people.
Going to look into some tips about cross-under and how to DIG that edge in some more...
I do cross-under sometimes, specially when dodging people; but my turning ussually goes back to cross-over. It just feels nicer, surfy... also, cross-under KILLS my thighs.
