When jumping the you and your ski are already moving at the same speed, so if you jump up to flip your own inertia will carry right along with the ski. If you try to jump forward to compensate for the movement of the ski you will end up on the hood. Only real issues I see with it is when you jump from the ski you will be in a since pushing the ski down and yourself up making the ski drop and get back to the water much faster. Also ,with the first issue, you will have to jump above where your pole sits, do the full rotation, then come back down and land other wise your feet or head will hit the bars mid spin.
So basicly what I am saying is go for it and get every second on good video. Cant wait to see it. (if you land it, no one will beleive it without the vid, if you dont... we all wanna see that just as bad.) good luck
