A couple thoughts: I know BT 7p won't quite hit after 44f+p 4k, but I'm pretty sure 7pp will interrupt if they try something. So it might move you close enough to try BT 7k. Also haven't tried BT f+k or BT 2f+k, but those might not be the worst options. I think turning around by holding 9 to 9p from BT might work well too; even if they duck 9p they might still eat the knee. I'll see how this goes.
The 3k/hold 3p/throw mixup is very safe from the 4k; I'd use it liberally. BT p+k and BT 8f+p are awesome but they are reactable. Once they start expecting them the part where you just kind of duck for a second and throw them can be quite a surprise. On that subject, anyone know the absolutely fastest way to turn around from BT? It'd be kind of awesome to get this setup right into 44p. At +18 or so you'd think it'd be fast enough to work.
Curious as to why? Preference for the immediate throw/mid mixup to the 46p/46f+p options? I haven't really tried this as a pseudo (I will) but I'm not sure if you're trying to throw why you wouldn't use 1p 6f+k? Slightly more damage and +9 is enough for most of the reasonable mid and throw mixups you might try. hold 3p seems to be kind of a bad compromise; it's not like it gives you enough frames to go for 8f+p or anything exotic. Suppose it might be better for 7k though.
