Vov, Hawk, Sandro Dias, Alex Perelson, Giorgio Zattoni, Richard..... fuck I forget his last name but he lives in Rhode Island if anybody knows who I'm talking about. He was in a Tony Hawk tour vid from like 10 years ago. Those guys have all done 900's. Danny way has not.
edit: I'm pretty sure Tony's the only guy who's done two different 900's but I'm not 100% sure on that.
