just commit. there's no magical tip that someone is going to give you on here if you can't provide us with video or photos of some sort. Just send it, don't open up and see what happens..or as TJ would say when it trouble tuck for double
My friend tried it last week-end, from what he said you have to throw real hard like throwing a cork 7 rotation, and continue your spin and hope to land it on your feet. He almost got a dub 14, landed it on his feet.
