Has a b/s tailslide hardflip out been done? Not where you do a body varial and land fakie, but a proper hardflip out to forward. I've seen b/s tail f/s bigspins out, but not this.
I don't know why I've been thinking of this dumbass trick recently, but - doing a handstand and rolling up a small quarterpipe, then doing an axle stall while still in a handstand, then rolling back in while still (still!) doing the handstand. Seems incredibly stupid and dangerous and groundbreaking.
Also my previous post, the switch f/s board pop-over to regular - Vincent did that in his Skate Sauce part. I should've known.
