So I can cork 5 and cork 7 on a trampoline pretty consistently to the point where there almost as easy as spinning a 3. I've been trying to learn cork 9's but I just can't get that last 180 around, and if I do, I land on my ass. Is there an easy method to learn these? Like do I need to start going off axis later or do I just throw a slightly harder cork 7 and spin the last 180 after coming back on axis? +K for legit answers.
