As most frequent followers of our site already know, I'm a fan of Eddie Bravo and his "System." As of late I have seen pieces of "The Twister" become more and more popular in big competitions. The Twister Roll can be a great path to the back and can lead to some really slick submissions. Don't believe me? Take a look at Cyborg teaching a guard pass - twister roll to the back ... and watch Ryan Hall do it to Hermes Franca.
Sick, I know.
Take a look at this vid from 10th Planet, Van Nuys. The Twister Roll leads to a slick armbar - tricky tricky my friend, tricky tricky.
