Dude, go with the 9 jump 2d, works like a charm. Plus you can put something before the 5b, like a 2b, 4b, jab, or my personal favorite, 6a. The mixup I've been trying to use is 6a, 5b, 9 jump-2d-j.a(have to input quickly to hit crouching opponents), j.b, dj, j.a, j.a, j.c, 2b, 5b... instead of either of the j.b's you can airthrow fake into a quick 2b. I don't know if this video has been posted yet, but I've been working off of it for a few weeks now. http://www.youtube.com/watch?v=rZ0DV0NT8Kw
