I don’t know if she has a higher damaging one… I think that’s about it. You got the jumping fierce/RH custom, and the standing RH custom.
for shits n’ giggles you could do the qcf+k, RH grab custom. Activate, get a knockdown somehow (sweep, KKK), then repeated d.fierce into run, hit RH for the hopping grab. As soon as she lets them go, do it again. To end it you do air 720 super after she lets them go from a hopping grab. Not the moment she lets them go (like when you do the d.fierce) but when she bounces into the air. Doesn’t do as much damage as the other CCs, but is a lot more stylish than jumping with the same attack over and over or mashing a button. Good to kill an opponent with low life.
You could also try corner custom with repeated fierce haymaker punches, then switch to jumping attacks near the end for air 720. I remember this doing good damage.
She’s got other stuff to play with too, try linking the CC. After d.strong or jab-strong chain. If you’re insane you can link it after jab-strong-fierce-whiff grab.
Don’t forget about her throw in the corner. She can combo her punch throw with CC. So you can throw, then activate (harder). Or you can Activate, then throw (easier). I prefer the latter because you get the CC freeze and invincibility which = sticky hands. After the throw I pop 'em up with d.jab, d.fierce, then do jumping attacks. You can do something else instead, but I’m a scrub.
