I normally do this:
BT Throw > H+K > 6P+K
It's guaranteed, and is the most damage I could find for something completely guaranteed that could also go into Rondo, from there I do something like:
BT Throw > H+K > 6P+K[4] > BT Throw = beats high block, mashing a standing normal, and high/mid Holds.
BT Throw > H+K > 6P+K4 > 6P = beats low block, mashing anything, throws, Mid Kick holds.
BT Throw > H+K > 6P+K[4] > BT 3K = beats low block, mashing anything, throws, mid punch holds
These three options pretty much cover anything, once you get into this setup, you can keep going until your opponent actually guesses right. Obviously you can go for a launch at certain points to get some guaranteed damage as well.
