Up rock incoming, ETA 5 minutes
Young Shang's Bed of Spikes has a ton of active frames. It's normally -28 or so and -14 for EX but when done meaty, I was able to get it as good as -4 and +10, respectively. B223 is perfect for setting this up, I think you can also do safe spike after the F3 overhead knockdown.
Combined with Sektor's missiles in the corner, you can combo and jail pressure with it, pretty neat! Jailing stuff with EX spikes was much easier when I was practicing on Shao, perhaps the pushback can make it tighter on smaller characters.
