I get the rotation now, I see...
Ok, to do one of these, you would need to carve into the jump like fuck if you wanted any chance of landing. Basically, its like a backflip, but make it so god-dammed off axis your head and skis rotate on the same vertical plane...
I've seen an off axis backflip, but the degree of this would be nuts.... it would be like that video of the cork 180, but continued around to 360 sorta....
