Seeing as you were kind enough to bump the thread, I’ll add a few more things to this thread. If anyone else wants to contribute, please do so!
Knockdown cross-up trick. I have seen M.Tsun on knocking the enemy down doing a juice kick as the opponent is getting up. If you do it right, it crosses up the opponent, hits them meaty to keep you safe and allows you to press home the advantage. It’s a neat trick because if your opponent goes for a reversal, his controls get switched, and because of the way the hurricae comes out, even if they input the reversal the correct way, they still have a large chance of messing it up. If you do this a few times, then you can alternate it by doing the hurricane early so you dont’ cross up. Of course the hard thing is to actually do the Juice Kick, but it’s a nice trick either way.
One other thing, my preffered combo when jumping over a fireball is Hard Punch X RH Hurricane, and Sweep on landing. It’s three hits, knocks down, and is very easy to land, unlike the jump in HP, stand HP, Jab Dragon, which can be hard to land on some characters (e.g. Ryu).
