the tricks that freak my out the most are:
1) switch tails. it just gets me every time. i way prefer switch lip to switch tails
2) backflip. i used to do them daily but years ago i got some weird pop off the lip and ate shit so hard. i haven't done a single one since
3) switch right takeoff. i'm good at skiing switch over either shoulder, so you'd think it would be no big deal, but it is. spinning right during forward takeoffs is no issue and switch left is no problem either, but switch right just feels wrong!
