Just watched your Rig power launcher video and it was awesome. I think you should enter one of the combos in the power launcher contest at www.pwnit.com. You probably have a good chance at winning and the prize is pretty good.
Idk if this has been posted before, but I came across this online and even though it's not 5U some of the stuff in this video may still be relevant to the current version.
It says that 6P+K has been changed to cause a sitdown stun (or ground bounce, not to sure which one) and it's -11 on block now instead of -6. Hope this helps somewhat.
