So I've watched the top ranking playbacks and still can't figure out how to hit that first water jet so it shoots you over the first part of the map. I was able to do it once, but I'm not sure what caused it to behave differently that time. I've tried approaching it slowly in a wheelie, fast in a wheelie, bunny hopping to a wheelie, etc... If anybody is able to reproduce what I'm talking about consistently, I'd love to hear how you're doing it. Cheers.
Completely unrelated: I hate that you can't add a message to a friend invite reqeust on xbox.com. Meh.
