Here's a midscreen combo I've been fucking with:
whatever, 2H, iad S, H, wings, FRC, dash K, 6P, 2S, sjK, S, H, key or D, wings
or 2H, iad S, H, wings, FRC, dash K, 6P, 2S, sjS, key or D, wings
The FRC is mostly optional, because it will work tensionless in a lot of cases, but it makes the rest of it a lot easier imo. For instance, I've never gotten it to work at max range on ABA w/o the FRC.
The 2nd "variation" is just what I like to call a bailout combo. Sometimes, my timing will be off, and I'll be too far to hit that sjK. Well, the sjS will reach in a lot more instances and still give you the key grab.
Also, I've also found that Furix's 1st combo will work on more chars if you can fit a quick dash between reps of the loop. It's pretty damn hard, but if you got the execution, I say go for it.
