I've seen Kali Tudo about 100 times and I think it's awesome! The Dog Brothers have really gone the extra mile with the Kali Tudo DVD and I think it will be a very long time before anybody even comes close to matching the sheer depth and quality of the techniques and theory presented in Kali Tudo.
In addition to the 90+ minutes of instructional material, The Dog Brothers have also included an indepth interview with Crafty and Top Dog, a real street fight from Mexico with knives and clubs that reminded me that the street is truly different than the cage, and a classic boxing match with Ceferino Garcia (ex middle weight champ who created the famed Bolo Punch that was later used by Kid Gavilan and Ali)
One of my favorite sections from the Kali Tudo DVD is 'Triggonometry'. Triggonometry is basically a footwork structure that you will learn once you see the dvd. I have been using Triggonometry in Fight Night 2005 for the PS2 Online and I'm absolutely destroying people left and right with the opportunities created by Triggonometry.
Now...if there was only a way you could do the Zirconia in the game...then I'd be the online champ!
Hoo Hoo Hoo (owl noises)
