He can't link s.lp into s.mp or cr.mp unless it's a counter hit. s.mk works regularly.
FANG isn't so much about damage as he is about frametraps, pressure and zoning.
He can, i just tried it out in training. But yeah his frametraps are pretty decieving, i just lost badly to a fang earlier today and i didnt realize how plus he was on some normals.
