Why limit yourself by training paradigms and methodology that is clearly not designed to support that goal?
Good point. This seems to be the basic question. I keep Aikido as my core because I want it to be my philosophy in life. There are techniques which I feel effective and there are some that makes me chuckle...i try my best to identify the "realities" of the need to defend myself and supplement my aikido with other things that I am more comfortable with...no specific prescription...again it really depends on your own goal as quoted above.
