I got to enjoy this today while waiting for a SAS program to run. Fun stuff! I agree that this guy has some nice, very practical street applications.
Oh and the other group... Don't get me started. They are the reason why I quit doing tai chi. Once upon a time I could walk through the Yang style short form. But the clowns I learned it from (one of them being a VERY famous American) didn't have a clue what the movements meant. Very sad.
These guys look like they're having fun, and that's the real deal. Look, ma, no chi!
