Just my observation, the TMAs are really concerned about their art being pure. "This is the ancient xyz" oh yeah we call that a kimura "This is the ancient abc". Yeah we call that a hip toss. They lose their minds and go on for hours about how all these techniques were passed down thru their art. To me it's just comical, there's only so many ways to twist a arm or choke someone am I really suppose to believe none of these arts learned techniques from each other.
