Well, since j.236D is high, I usually mix it up with 2D to go low. The 2D combo is basically the same, but the start is: 2D (1 hit) > [4]6H > FRC > 6P > 6H...
If you get a c.5S hit, you can also do the combo. c.5S (3 hits) > 6P > 6H...
Those are my usual starters. If you catch someone in the air with 6H, you can summon a P ball straight away and again go into the same combo.
It's basically anything into that combo
I also have a version of that combo that includes 6P > 6H > [2]8S, but it seems no one wants to learn that =_=
In case anyone wants to try: (starter) > 6P > 6H > H ball > dash 6P > 6H > [2]8S > 6H > P ball > dash f.5S > Dubious Curve or 623D
