Same damage and pretty much the same combo except I switched out neutral 4 for B12. I mean, she has sais, you're playing the piercing variant and the last move she does is called Sadistic Ways. Why would you kick instead of stabby stabby?
njP TK xx Air Sai D2 (side switch) B12 xx Roll (side switch) walk forward B21 2+4
EDIT: "A 'true 50/50' is used to describe a mix-up in which the defender must guess and commit to one option, without any way to determine which option the opponent will choose and react accordingly."..wait when you say mixup starters aren't 50/50s do you mean like the "21" part of 21U4 isnt a 50/50 or do you mean something meaty low/high on wakeup isnt a 50/50? Cuz I thought you meant the latter isnt a 50/50 but after re-reading it I think I misinterpreted your post.
