Darkshine, this is how to do it on stick:
Step 1: See if you can air brake (air dash with Faust and then FD)
Step 2: jump up, airdash for a little while, and then FD
Step 3: Jump up, roll your stick back 2->1 (well, DB at least), and then DRUM your FD buttons. For example, if you use P and K for FD, hit P then K in succession. LISTEN to the sound: if you can hear a gap between the buttons hit, then you're hitting them too slow. If you're just jumping up and FD'ing, you're doing it too fast. It'll take practice, but eventually you'll get it to work.
Step 4: Add spices, rinse and repeat. you should "practice" using it with HS, since you're less likely to be punished than with K if you mess it up.
I got a question: what can I do after a cancelled punch? After 2HS/5S -> P/2P/(item throw), are there many options? All I usually do is either 2HS ->P ->5s->236S --> air combo or 5S -> 2P/(item throw if too far away) -> (if I'm close) 2D -> 2S -> K -> air combo. I've also done stupid things like 2HS->P->5S->2P, etc. but I'm wondering if there are any other options.
