4[A] seems to be his most reliable tech crouch, which is great because you can turn the momentum around and start a frame trap or unblockable of your own. Really useful in tough matchups like Nightmare whenever he goes into NSS at close range.
44A has backstep properties, and is great for making...
I'm loving that 3B 1(B) reset that Toilet's doing. It almost makes ZWEI look like he has good oki, lol. Still feel that anyone with good tech crouches and range poop on him for free though.
