I'd think you need to push the crossface over and go for the triangle there. This past week I got into a half guard battle with a guy i've been working 10pjj stuff with. He went to the twister and i sat up, and seat belted him as he was messing with my legs. I don't know if I had anything from there, but he quickly stopped the twister pass and turned back into my half guard.
