I haven't gotten a chance to play BB yet, but I was thinking, if the Bang is doing what Dora did in that one match where he flew along the top of the screen, couldn't you just catch him with 632146C while you're near the corner? Likewise, if he throws the nail to go accross the top of the screen, can't you just go to the corner and 6D the nail? He can't block in bang install mode (outside of FDing at the end of dash recovery), if you catch him with wave super or a counter, he'll take amazing damage.
