IIRC, Brushie's jump was during the era where you had to race to win the overall. If that's right, then I think that move was not only a stylish joke but also a middle finger, as if to say "we shouldn't have to race". It was obviously an event he didn't give a rat's about either way. Completely different situation. As for Lindsey, put me in the showboating camp. Not saying I wasn't that dumb at the ripe old age of 20!
I agree with Neil, grabs are necessary to get into the right position. Can't tweak without a grab. A method without a grab is just... fruity. Rails on the other hand... now that is just skateboarding for dummies.
