I learned not too long ago that ex nut punch has some invincibility frames on it (that or I forgot since i read this in tom brady's TYM guide lol). I tested this out against SZ's 212 and raiden's 334 and it interrupted their strings. I haven't seen this too often in high level play (or any JC players for that matter).
I highly doubt this is new but I thought I'd point it out.
