I think dub misty 9 looks sick. I think I have seen bobby brown and peter o do them. Dub misty 12 probably could look good on a bigger jump and with a grab.
Bio's always look hucked, because you have to huck them to set them... corks you drop into and bios you huck. Also it would look way steezier if there was a clean separation between the bio and misty and if he had actually gotten the whole 720 rotation in the bio before setting the misty.
