so this season i have learned 3s, 5s, and 7s off biggish jumps(like stuff more than progression park kickers). i can sw 1 and do 1s and 3s with tail and safety grabs. on rails i can do both way slides and both pretzel 2s out. i can do 3 out of 4 270s on to a flat box and sometimes get all 4 switch ups. i have about 5 more ski days and i really want to learn to flip or something difficult like that. what should i try for my next trick? like whats the next step?
