1. Approach the ramp in a downhill trajectory, with no regard for safety.
2. Catch an edge just at the lowest point in the approach
3. Fly forward head first, burying your head and shoulders to about mid-shoulder.
4. For extra steeze points, bone your entire body on impact so that it extends rigidly up from the snow at an angle, before relaxing and letting yourself fall to earth.
5. If desired, you can hold up a cartoon sign that says "Medic" at this point.
To the op you cant really control yourself in the air. Most of what you do when jumping happens on the jump face. I like to pop off both feet cause I think it's pretty easy and when I ollie off a jump shit seems to go all haywire. As far as approach goes I will speed check a few times just because. Speed is probably the trickiest part of hitting bigger jumps but in my opinion coming in hotter is way better than coming in slow. You're first and second time you might die crashing but when you finally land it its so awesome. And when you get better you land it your first time fairly often.
