I really don't think they're doable, I've spent so much fucking time trying them. But a backtail, shuv-late-shuv looks okay if you can get it where you roll the right stick around a whole circle. The board never stops moving if you just mess around with it for a while. But I've accidentally done noseslide 360 inward heel, 360flip, and 360 hardflip out (yes, all on accident)... so I keep my hopes up that somebody comes thru with a tutorial.
I just re-read that and fucking hate how much of a geek I am. But it's -10 F out so whatever.
