So I thought I’d just suggest a few SS dive tips for irregular wake-up characters.
For Zangief, T.Hawk, Guile, Sagat, Adon and Vega, slide/press, c.mp/buffer 360 into back walk, lk dive works as a mix-up, although I wouldn’t recommend it for Vega, for obvious reasons.
For Chun-Li and Ibuki, slide/press, s.mp/buffer 360 into back walk, lk dive works well, as they wake up faster.
If you do typical SS dive set ups for these characters, they are able to jump out of them, unfortunately. Chun-Li and Ibuki require earlier timing, too, so that ruins easy mp rocket, forward jump, mk dive for them, sadly.
Against Sagat in the oil trap, instead of oily f.hk, knock-down, back dash, walk forward, lk dive, use walk back, mk dive. I also recommend against these characters, when oily, instead of oily slide/press, back dash, walk forward mk dive, use walk back, hk dive. Do it a couple frames quicker for Chun and Ibuki and slower for Gief, Hawk and Vega.
Lastly, a nice technique against Chun Li is slide/press s.lp, neutral jump hk. It’s safe against EX bird kick!
