David Porter, black belt, & his new DVD on the Brabo choke
b'Since we last talked to David Porter, he\'s earned a black belt from Pedro Sauer, produced a new DVD on arm-in chokes ("Bringing Back the Brabo") that drops this Friday -- and he\'s also got an awesome story about his trip to Australia, which involves a great ape, a koala and kid with no sense of self-preservation.'
