Cesar Gracie vale tudo

what do you think of the vale tudo/street fighting techniques shown on the Cesar Gracie Jiu-Jitsu dvds?

They are some of THE best instructionals you can find on BJJ. He covers a broad spectrum of jiu jitsu in respect to bjj training/tournaments, vale-tudo, and self defense. They are a steal at $60.

One of the best parts of that set is when it came out in VHS they included a 10th tape that shows Cesar punching out three or four guys at a casino. It was caught on surveillance cameras. It was hilarious. I sold my VHS tapes to pay for the DVD but kept the 10th tape since the DVD doesn't have that fight in the set.
