i would suggest trying on a wakeboard as well.. (sure its like cheating, but..)
i rode this weekend (@ koppert) we kept driving so close to the rails and i kept think just go hit it.. (last time i "pacticed" them on a wakeboard then a skate)
so with out even wetting them down i charged the rainbow rail.
went on 5050.. the board slid out and ended up in a front side "rib" slide.. and im pretty soar.
my son said at least you landed it.. the rib slide.. first try..
have fun and be safe.. as you can.
