So I've been having this problem with almost all rails. So I ride up to the rail, and usually I split my legs around the rail and I jump to a 90 and I almost instantly slide off the left side (I get on with my right shoulder forward ) and I ALWAYS land switch. I talked to a few guys at my park that can do it, and they suggested trying to spin 45 and locking on, and it worked... the first time. I walked back up to hit it again, and its like it never happened. Same problem. I decided to go back to some boxes for practice and I have no problem on any boxes. I can hit boxes and land almost every time switch or regular. I understand the idea of scissoring (angling my skis) but its just not working on skis. I tried to get on urban and it helped and I slit maybe for a few feet more, but then I slipped off the same way, IN SWITCH. Its been 2 weeks and I'm having the same problem and I just can't fix it. I've talked to many park riders and none of there advice has worked (or maybe its me).
Any advice would be GREATLY appreciated!
