For all else that has been said....my initial response was to the idea that a blending style of Aikido handles all..... I know people who you can not feel move, you can not feel their intention to move...you can not sense it and once moving you can not blend with it.....you are just at the effect of it.
That is not to say you can not reach a level where you are the one that moves without others awareness.....maybe with the ability to "blend" early enough so the attack doesn't happen... just hard to reach at half that level....and there doesn't seem to be much interest in doing even that .....so.....
I agree with that too. I believe the blending style does indeed handle everything once you can do it of course.
