Hey SRK, so today I did some brief labwork and found some option selects for hard knockdowns (both regular and DWU).
Oni’s sweep has gotten buffed in Ultra (1 start up frame and 1 recovery frame were taken away) making it and even better footsie tool + OS tool. Oni also lacks special moves to option select with (his Light demon slash has too much start up to OS with), making the sweep essentially the only OS option he has to catch back dashes.
For most characters, using Cr. lk > Cr. lp + Cr. hk works because Oni’s Cr. Lk like most shotos has a recovery of 9 frames and is also chainable to his cr. Lp. However, for some characters with godlike backdashes this simply wont suffice. For characters like Vega, Chun li, Makoto and Rose you may have to simply OS using his Cr. lp because his Cr. lp only has a recovery of 5 frames.
For the delayed wake up set ups, they all begin the same way as the regular set ups. So all you have to do is watch for the technical and use the appropriate set up if you can react quick enough. Enjoy and if you find any errors or better set ups, please let me know and I will update this thread!
