This is probably old, but I’m posting in hopes that it isn’t…
Instant Ultra 2 (IU2):
From what it looks like, the ultra comes out the moment Gief leaves the ground. Not only does this make the ultra 2 unexpected, but since you’re grounded it gives you the option of using Gief’s other command grabs.
I like buffering/storing in the 720 with normal attacks/block stings/dash
-Far s.FK [buffer 720]
-c.lp, c.lp, s.mk [buffer 720]
The 720 doesn’t stay stored long, but you can increase the stored time slightly be constantly buffering in 360s.
Mixing it up: Nothing fancy here. After imputing the motions, you have an option of either going for an EX RBG or an IU2 depending on what your read of your opponent.
Also, if your opponent has meter, you can buffer and bait an attack and go from there as well.
Against wake up, this works pretty well. Bait a wake-up DP > IU2 grab…
