dunno if it’s already common knowledge, but some weeks ago I was messing with the mk.tatsu => mp.srk / hk.tatsu juggle and I found something interesting.
beside the fact that vs some character seems harder (or impossible?), I found that vs Necro and Chun you can connect HP.srk instead of mp, and it’s WAY easier (stun and damage are pretty much the same btw).
I think this can be pretty useful against Chun when you connect a low parry and you are close enough: way better damage & stun than simply doing c.mk xx hk.tatsu and don’t need the SA for the big damage.
dunno if works on other characters too, I tested against those two cause I happen to fight them pretty often
