She does have quite a few sitdown stun, but they all blow the other guy across the screen. So far, I've only found 8P6P 236P 66 7P/7K, stun 8P6P 7P/7K, and 3K4K P+K 7K to have the followup guaranteed (fastest SE).
Biggest problem, I think, is my reliance on high stun extenders and mid punch approach tools. I'm experimenting with Stun 3KP 9PP2KP (or 9PP2K delay K for a +20 force tech) but I'm hoping I can squeeze more damage in there. As for getting in, I'm trying 1P, but both the followups are beat by 2P and by itself, it's -10 (and -7 on normal hit). 1K is decent 'cause it has good followups, but it's really nothing to write home about.
