my brother always said he'd be the first to hit a 12 because he was so smooth on his spins... too bad he was beat to it but I wouldn't doubt if he is the second or third to nail it.
Thanks for the list Andy. There have to be many more guys that are close. It's definitley cool to see somebody new take down this trick, but it has lost some of the "wow" factor now. If you're wondering, then no, I haven't landed one yet.
