So, I've had this in my head for a while and have yet to see someone do it. Hard to explain but here goes....Basically it's a switch double 10' with 2 grabs. Take off would be a super slow stretched out nose front left ski, almost like they set for a switch cork 7, but then as soon rider starts to go inverted they would pull it up into a mute (Naturally speeding up the rotation). Basically you're stalling out a double with 2 naturally flowing grabs. Idk, just a thought. Think if someone could sync it together it would be the holy grail of doubles. Rotation control needs more love in the double scene. (Not a double but @ 0:47 is similar to what i'm talking about)
