Master Harris was at our expo last Saturday. Here's a few clips from the show... (forgive the video quality and inconsistency...I am yet to get a new iLink cable) Kata (944 KB) When someone attacks you from the back...(145 KB) Progressive neck strikes (226 KB) I wish they did more explaining during their demo, though...
You're welcome Recognize the Kata? I've never seen a Kata with a cartwheel before Looked incredible, though (the whole Kata, not just that part).
I think those guys are American Kenpo, I do Shaolin Kempo so that kata are different. We don't have one with a flip in it as far as I know. I wouldn;t try to guess if that is "official" AK.
