That was an excellent read especially with Roy's perspective on the TMA's. I have felt what he is talking about when I have been an uke for Marcio. His technique is so sound that the small amount of strength that he uses is overwhelming.
One of the black belts that I trained with many times would tell me to quit muscling everything then when we were grappling and he didn't like where we were he would use strength on top of his technique to move out of the position. I got so frustrated one day and said man you use strength and he replied yes when I need to not all the time. That was when it kind of clicked for me.
What we think, or what we know, or what we believe, is in the end, of little consequence. The only thing of consequence is what we do. -John Ruskin
