Whats the difference between these two systems? Did the Machado´s train in the Gracie system at one time? I seem to remember an article saying they were cousins,true? I´ve also read that of the 2 camps. The Machado´s are the more amiable,true? If so how does that play out in the training. Comparing one to the other? Just questions of curiousity. No offense intended to anyone,o.k.!
