How is the Renzo/Kukuk DVD's?

I was wondering what the information on the original is like. The one with Renzo and Craig Kukuk. Anyone?


I thought the fight footage was the best thing about the DVD's. If you want the basics, I would go with Cesar Gracie or Kukuk A-Z. The Renzo/Kukuk set is very spartan in technical details compared to the other sets I mentioned.
