just try it first than ask for help. everytime i get someone on the hill asking me what's up with rails i explain the whole sholder width apart, look at the end of the rail, center balance shit but i have yet to see one person do good their first time. you will most likely have your feet to close togeather and eat shit - that's good. you won't make the same mistake the second time. who cares if you get hurt, just try it again and you'll eventually get it right in your head. rails arn't hard, you just gotta figure them out.
