One of the guys on the XX board lost both his legs in a bike accident ~5 years ago. Bike pinned him against a guardrail IIRC. Todd's gone down the dragstrip since, in a similar setup to what you're talking about here I think.... Though IIRC, he had friends at the start to spot him while the tree was dropping, & more at the end to help him get off Also.... At the NeXXt meat 2 years ago, there was a guy with a ZX14 & a hack with a reeeally sweet suspension setup. They were thinking about that for Todd as well. In fact.... I think he even took it out for a test spin
