Nice combo. Kinda weird how the rekkas hardly add any extra damage at the end, but I guess every hit counts.
As far as air-to-air goes these days, I've been experimenting with j.A a lot more since it hasn't been changed from the PS2 version. The hitbox is still very large (much larger than most other character's j.A hitboxes), and covers more horizontal / vertical range than j.B (plus it's 1 frame faster to boot). The trade off is that her hitbox is included within it, so getting counter hit in the air is just as dangerous.
So in a nutshell you have to play chicken for your air neutral game and go aggressive for your ground neutral game. What a strange character.
