Three:
Tom Penny's pop shuvit at Tuggeranong, don't know the video and I think it might have been shot in 16mm so doesn't really give the scale of that trick the justice it deserves. He pretty much shut down that trick with that one.
Phil Shao's Smith grind on the wall thing at Tampa, particularly the exit - you know the one
Rick McCranks FS flip off the little bump during that comp, I argue one of the best ever done. That catch....
Edit: Any slasher ever captured of Scott Oster, FS or BS, it doesn't matter. Both incredible. First time I ever saw footage of his slashers changed my appreciation for the trick and they're burnt into my mind permanently.
