let me tell you, trampolines can improve your skiing ten fold, this summer i got a fly bed and put it in the ground and in the beginning of the summer i couldnt even do a seven on it, but now i can do cork 10s both ways, now whether you do tricks straight off the tramp is up to you but i gaurantee you that if you find yourself accidentally off axis you can bring it to your feet and people wont even know that you didnt mean too. this all goes back to "air sense and trust me i did alright before the tramp but no real flips and off axis things and now i feel that i can play around with axis and it makes skiing truly fun, in case it wasnt already. I hope this helps.
