Personally, I've never even seen a real sized half pipe to ski on so I've never had the chance. I can skate pipe, granted thats different but I feel like it'd be better than going in with nothing.
I suck at pipe, my home mountain's pipe is only open like 2 weeks out of every season. I can air out of one about 10 feet and do little 180s and stuff though, when I go to Mammoth mostly.
I just can't do pipe. I have such massive respect for the guys that throw down in them, because I'll be all set to throw something but as soon as I'm going up the wall my balls shrivel up like raisins and I do an ugly-as-sin 180 then sketch the landing. Pipe scares the bejesus out of me.
