you can throw it on a tramp, it's just pretty hard and quite a bit different.
If you are going to carve for your corks (on skis) you have to just set it lightly. It needs to take very little motion while you're in the air. And it's alot easier to do them on bigger jumps - 40 to 60 foot table should do it.
For carving: come into the jump, keep your body relaxed and loose. just lean into the spin. If it helps try tweaking out a grab, or just lean into an inside grab (grab left ski left hand and look down towards the back of your foot)
you need to keep your body relaxed and just SLOWLY come back around without making much movement at all.
Eat. Sleep. Breathe. Ski.
