purchase a large pair of balls from your local hardware store and go for it.
but for real.. just watch a couple people take the jump..watch the speed..ask for the speed..try and size yourself up with someone around your height and weight and watch how fast they go. you can also follow em and then veer off at the end just to take a manual speed check. then all u gotta do is just huck it and stomp that shit...n then u can be like 'bietchhhh!'.
