I just do the entire air string as fast as I can. My best guess would be I throw earlier; looks like she grabs them OUT of the pillar when I do it, you can do it deceptively early in my opinion. Also you have to be careful not to fly forward a bit and lower yourself. I wouldn't say I can do it consistently though, as I rarely make it past the fly cancel.
j.6B xx 236A only works in the corner though, since I forgot to mention it for some reason. Midscreen I do j.6B ad j.C instead, leaving out the j.C if I don't think they're going to be low enough.
Edit: Tested it a little more. Just in case this might be the issue, it REQUIRES 7 or more hits before the 2C to work. Just tested on VSion, Len, Akiha, and Miyako, works on all of them as long as there are 7 or more hits after 5A6AA.
So 2A 5B 5C 5A 6AA, 2A 5B 2B 5A(whiff) 6AA, IAD j.B 2A 2B 5C 5A 6AA, low crossup j.C 5B 5C 5A 6AA starters. Anything that isn't in deep, that gets fewer hits, won't have the gravity to work no matter what I try to do differently.
I really need to get the 214A xx 22D > j.A link down so I can use this more.
These are what I actually tend to use right now when I get to play:
5A 5B 2B 5C 2C 214B > 6C sjc j.A j.6B j.B(1) j.C sdj (very slight delay) j.B(1) j.C j.22D > j.A j.C air throw
Works even starting off a max range 2B, but the air combo is harder with that few hits. Midscreen you HAVE to either hit this from pretty far or leave out the 6C (or use some retarded string like 2A 5B 5A 6A 2B to push back). 4435 damage on Akiha.
2A 5B 2B 5C 5A(whiff) 6AA 2C 214B (6C/3C) sjc j.A j.6B j.B(1) j.C sdj j.B(1) j.C j.22D > j.A j.C airthrow
Basically corner only. If your opponent's back isn't against the wall after 214B, you have to save the combo with 3C instead and suffer the horrible proration. 4523 or 4428 damage on Akiha, depending on 6C or 3C.
The great thing about these combos is of course that you're still in flight mode after the air throw and can throw out whatever special you want or airdash.
5B 2B 5C 2C 214B j.A j.6B j.B(1) j.C sdj (very slight delay) j.B(1) j.C j.63214C dash 2C 6[C] sjc.B(2) j.C dj.B(2) j.C airthrow
For when you're sure it'll kill and you have the circuit. Absolute highest damage I can get personally, 4880 on Akiha. I think it might be possible to get a 5A(whiff)6AA in there, but my 6[C] towards the end OTGs every time I try it, probably just not hitting the 2C high enough. Vid here because it's awesome.5B 2B 5C 2C 214B j.A j.6B j.B(1) j.C sdj (very slight delay) j.B(1) j.C j.22D j.A j.C j.63214C dash 2C 6C sjc.B(2) j.C dj.B(2) j.C airthrow
Does 4920 with the flight cancel but you can't charge 6C. 4764 off a 2A. This actually does significantly less damage and is much harder with 5A 6AA lol.
