I'll make a really long post here in a bit (But later, I don't really have time for much right now), seems like you guys could use a good deal of clarification.
I'm going to start by saying Bang's highest threat attack is his 5A, for sure. His drives are gimmicks and his pokes will usually get beat straight out by your 5C, but his 5A is going to give you hell. Bang can IB 5A on pretty much all of your 'safe' block strings, so dont get too comfortable and don't let him get away with it either. If you're playing a bang that likes to IB/interrupt, you're going to have to find some way around using the lengthier blockstring moves, like B sledge. If you can somehow make him scared of even trying, that would be great, I just don't know Tager well enough to know how you would do that.
But yeah, if you guys could bounce some stuff off me I could give you Bang's dangerous answers to it and etc. GL guys, Bang is going to be one of your harder matches overall.
