i think you should start working on more of her combos that involve tsubame. one i learned that helped me a lot is
(near corner)5B, 5C(2) itsuuC, j.B, JC, j.B, j.C, D falling j.C, staff 2, (land)6C, tsubame, 6C, 3C.
once i learned this i learned a lot of her other more difficult combos (6B/j.C CH, throw combos, and even staffless combos that end up with you and your staff on opp. in corner.
this also introduced me into litchis pro corner game, i got a lot of wins with even the simpliest tech traps, and my friends were quite (GRAAAAAWRRR) until they figured it out. then i learned how to vary my traps. more (GRAAAAAAAAWRRRR.) etc.
as for more ways to use the staff, Chun's thread has some neat info if you want to find more info out of this and some of the other threads.
