There's no matchup thread for Viola yet? I can't find one anyway, don't wanna make a new thread, it's not my SA. But I think that's a PRETTY important matchup thread to have, lol. Make sure you're stepping her 44A EX to the right, but don't run back into the ball. So far, all I've got is that if she does 44A EX and blocks in place, aB will catch her block at the very tip. Will Viola stand still and guard after 44A EX? NOT LIKELY. But just to give you an idea of the range you're working with. If you move forward AT ALL after the sidestep, you will get hit.
Even if you just step it and take back your mid range, you're in good shape. Seems to be where you want to fight her when the orb is out, mid range.
