Personally, i think his toughest combo is
J hp x s mp, cr hp, vtrigger, s hk, s lk, h srk, ca on P1 side.
Though now by adding a forward input after the h srk, the CA comes out consistently for me.
I can help you with the CA portion. I’m going to be using a clock hand analogy for your joystick.
If on P1 side, aim to stop the qcf motion at 2:30 when you hit that punch button.
On p2 side, stop at 10:30.
Let me know how that goes.
