Time to work out some safe jumps and ways of safe presure chaps.
What i have vs sagat -
cr.jab > cr.jab > st.jab > TC xx MP.Sekisei Jiraiken (for the untechable knock down). Then walk back abit and jf.roundhouse.
If you space it correctly you can make all DPs wiff and option select DP to catch back dashes. Problem i find is its really hard to get this consistantly - sometimes lp.DP will hit, sometimes ex.DP will hit, but sometimes you can get a really deep jf.roundhouse crossup which is rediculously ambiguous. Another problem is you need the combo before hand so you are pushed out enough to get the jump a the correct distance, but you can land this combo of just about anything with 2 meters.
edit:
You can also do cr.jab > cr.fierce xx Sekisei Jiraiken walk back jf.roundhouse OS DP. This will make MP, HP and EX wiff but LP will hit, the OS DP beats back dashes and punishes the wiff DP but, sagats rarely back dash to get out of presure and you get next to no damage on the wiff punish with the DP OS
