So I've been doing my combos, so that there's always enough gravity to end with B321 EX low hat.
With that, i'll hold the hat until they get up, and do F4. I'll be safe because the low hat will stop them from punishing.
Edit: To expand on F4, once you land it, if you held the hat as long as possible, you can do another F4, even if they don't wake up right away, or you could grab or pressure them as they block the low hat. Well after they block it with the grab and as with the pressure, but you get the point.
Or i'll let the hat go and do run into B321. If they thought I was gonna F4 first and eat the low, I get B321 spin off of the low hat after a short run, and get a 34% combo.
Edit: So you can do like F4 while holding the hat, then while they're getting up if they expect another F4, you can go for B321 into a full combo.
Imo Buzzsaw is Lao's best variation now. That has nothing to do with this gameplan but I figured i'd just share that opinion.
