Well my kendo guys weren't nearly as illustrious.
I am still wincing at the idea of ma ai being maintained during the entire execution of technique. During the initial phases of many techniques I often expound on the fact that ma ai should be maintained (ie. stay out of reach of the punch) but there comes a point where ma ai gets tossed. Because of kuzushi, body placement , etc. the danger from uke is mollified but to say you are sitll in ma ai - I don't know.
