A few combo that I haven't seen listed before (Edit Well damn. Missed the boat on reading posts. Oh well.) :
(Corner) Throw, 421K, 5K, 6P (hit Kball), 421K, S ball, 2S (hit Sball), 421H, Sball
Stolen from http://www.youtube.com/watch?v=YkRKD_3-wPk The Venom loses but the combo is still quite solid. This gives you a decent 20% or so, plus a nice ball set up (2 electric balls, 1 normal ball) for cranking dat guard bar. Feel free to change that last DBC and ball summon to anything you like for ball setups.
I'll probably be editing this post/adding more posts as needed.
Also, late replying, but:
That's pro as fuck. I'm going to have to try that out.
