Just watch the first jump in this video. He starts with only backflip, and then moves his arms to get some fake spin going.

So anyways I think dumont is nasty as anything, but his front flip to misty 7 is just a front flip aerial. He does a straight front flip and then starts himself spinning with his arms. Its cheap spin though, not real.
its at 125 in this video

So anyways i think Deschenaux was right about simons front flip misty, it really is an aerials trick which is kind of gay. Kangeroo flips are def not related to aerials i dont think.
