you could always pop VT1 relatively safely. VT2 has a lot of the same confirms but you actually have to confirm it. the fact you can't AA using VT2 into big damage is a turn-off.

mashing full shinryuken into CA is kinda nice, but that's a lot of resources to sit on. like I said, I got to play with it more but overall I think VT1 is going to be the better choice for most every match-up.
