Well, that's true for a parry (4G/1G) in some situations/characters (like when 4G/1G leaves the opponent right next to your feet), at least from what I've tested. From that, I can get a low throw opportunity if the opponent techs forward, left, or right. The 44B+K aGI seems to catch all tech though. I guess I might've been a bit confusing since I referred to it as a parry in my previous post (blue sparks make me think of parries, heh). I tested 44B+K a couple days ago and was able to catch all tech, but maybe I'll give it another shot this weekend.
Eh, I don't think I'd ever try using 44B+K on Hilde, unless the Hilde player was being really predictable with her charges/moves or something. But even then, there are better options at your disposal.
