Thanks for the replies guys.
I'm a bit confused between the last two messages. The two statements in bold contradict each other, no?
cadencesdad, you are correct about the goofy/counterclockwise thing. I'm kind of flying slightly 'backwards'.
Ya, I would say you may already be a bit to much toe-edge.I would start off by making sure you are coming off flat based. If you are confident you are coming off flat based already, perhaps a slight heelside may help counter your slight spin. Like mentioned earlier...Throw in a grab to help keep things straight. Also, some grabs will help initiate a spin. But you said it happens during straight airs too so.... Indy grab would probably work best in diagnosing the problem.
