Could it be that guys like Mike and Rob etc...have basically isolated and refined methodologies for teaching these things, yet maybe most of them cannot bridge the gap to demonstrating incorporating these skills in a much more alive environment?
I should say that at lest Rob puts his stuff on the line - outside of aikidoka and taiji practitioners.
Rob, you know I love ya, but I know you aren't falling back on that tired old "rules" argument, brotha. Let's not have to fight "no rules" next time you are out. After getting eye gouged by that Systemite to so little effect, I'm gettin' too old for that kinda stuff.
