The x games course rails are fairly burly already. Last year they had a decent sized dfd, a huge ass cannon (it scared the shit out of me at Aspen Open and I think it may have been slightly smaller at that point) and a big ass rainbow. No matter what though, it is stupid to have rails that are too difficult to make consistently at slope comps. When they do, guys stop tricking them and just hope to make it to the end where they will maybe spin out. They used to have longer rails in comps but it is dumb to watch a bunch of dudes try to straight slide a rail. There is too much luck involved and not enough skill.
