Good job, Spark. By the way, I don't know if you've seen how Lord Knight breaks down matchups in the Litchi forums, but if you haven't you should take a look at some of his posts. He does a pretty good job and the way he does it could be useful to bring on over here. (Actually, now that I look, it's pretty similar.)
There were some 2A option selects for dealing with some of Bang's pressure / command grab setups, although I'm not sure how much of it carried over from CS1. If someone knows what I'm talking about (huey) then it'd be nice if they could drop that here. You hit 2A (without IB) after Bang's 5A, and if he goes a command grab or various attacks, you land a CH. The other attacks are airtight and keep you in blockstun so 2A never comes out. I think there's one situation where you'd eat a combo, but all the other routes Bang could go would end up in your favor.
