At the start of the match try using Backstep -> Deadspike
very funny to watch Haku eat this over and over
Also on hit or block you can combo into 5b 5c HF+ Addition
That starts your wakeup game.
from what I can tell, it seems that going for an early knockdown is a bad idea against Bang. So any extra hits you can get on him is preffered to playing it safe.
Just throwing Ideas out there.
Personally I'd use 2k->back step VV (forgo the knock down) wait for Burst, BBU, and the like, run forward 2k->WT.
What I would like to know is when do you burst? Incredibly tempted to after BBU...
