SRSH[A] is terrible anyway you slice it. 66A isn't that great of a move. I rarely, if ever, use it, just because it's slow and high. 66B, neither, because it's not exceptional enough at tracking to justify -20. Also, Sophie and Xianghua can and will punish 3, and also 11, but they're all yours from WS. 4[A] also isn't something you should just throw out and hope it hits, and DEFINITELY not something to interrupt with. Other than that, it's just you attacking from disadvantage and getting punished. Very nice roulette, though.
Two things I think would help your game are throws and a+ka2A. Throws just because, hey, they're throws, they're great. Never mind that Sieg has low throws. They're a part of every character's game, and you should definitely add it to yours. And a+ka2A just because it's a great low. Practice it, it's not that difficult, especially with a binded A+K.
