Their "fundamentals of empty hand fighting" tape is pretty good.
Again I like it because he stresses the importance of strength.
The principles and theory discussed on it are all very good assuming that real fighting involves two people standing sideways to each other in "karate" or "kung fu" stances.
I suppose the material could be extrapolated and applied to any fighting scenario (ie, facing head-on like boxers), but the examples given in the tape are all with sideways stances.
They also kind of assume that your opponent will throw a punch and leave it out there. I hate to say Green Dragon falls into this cliche, too, but if I remember correctly (the examples I'm thinking of), they do. One of the examples shows Sifu Allen's "opponent" throwing a punch and Sifu Allen knocks it away really hard showing how you can knock your opponent off balance and make him cross his own centerline thus exposing himself, etc. Good points, good theory. However, it probably wouldn't work against a trained attacker (read: boxer).
People have said this tape has more info than you would learn in a year at a "normal" school. I may agree. There is some good stuff on there from a TMA perspective. I'd rather spend one day at a MMA gym, tho.
