I've tried an octo, just I couldn't get my skis back in time to land. Which didn't turn out so hot haha.
My hill doesn't really have a "good" jump for doing shit like that, which takes a long time. Instead of building jumps with lip, they build them for gaps, which you barely get any air. I'd prefer a 25' jump with a shitload of lip rather than a 45' with none.
