BTW, with that CH 6A combo..
Drop the j.C after the IAD.
After messing around for awhile, I get this:
CH 6A > IAD > Late j.B > Land > 6Axxsjc > j.B > j.C > dj.B > Allegretto.
I'm sure you can mix and match aircombo, like you already stated.
Combo'd on Tsubaki fine, for about 1.9k.
Not much more damage than CH 6A> j.B > j.C > dj.B > Allegretto, but it's enough to use it, since it seems like it can be done consistantly.. Totally worth the extra 200 damage and the flashiness.
Maybe something will come of this. I figure if it combos on Tsubaki, it should work on almost any character.
