Chou Jaio is her best style. Ba Guy and Kriss are good but are transitional at best. They have some good set up moves though. It's important to use all 3 of Ashrahs styles and know them well.

stay in Ashrahs weapon stance as little as possible!!!! ull do more damage to urself than ur opponent....
Chou Jou is the best and u have to be aggressive mixing up the combos both high and low
if u go into ba gua u should either do a trip into free throw or that annoying chicken leg but as far as it being her best.........hell no;0 its stay in chou jou and utilize low pokes

I think you should stay in the style you like best.
