I don't post here often, if EVER, but I just noticed yesterday that 3K has throw invincibility for what it's worth. It still doesn't seem like a good idea unless you can somehow guess that you are about to be grabbed(not likely most of the time). I figured I'd share it since I've never seen that little tid bit posted anywhere before.
If you manage to connect the 3K, depending on distance/whether you got a CH or not, you can try 236HS~K Fuujin, 5P, On...then whatever.
