Yeah, only in the corner the Jumping D, Dragon Tail B into whatever will work 100% of the time.
Any interesting Grab Super setups you can think of? The one's I got:
B Sweep at just within mid-screen distance, C Grab Super.
Jumping D, B Dragon Tail, C Grab Super.
B Sweep, B Dragon Tail, C Grab Super.
That and the generic poke standing B or whatever, make them think you're going to do standing D and C Grab Super.
