I've trained with Michael a few times. The Bill Gleason workshop was at his dojo. Unfortunately I have had run-ins with some others at that dojo (never had a problem with Michael), so I won't be training there on a regular basis. Still, some of his students train with us from time to time, and we are sharing ideas.
OK, well, just keep in mind that if you're gonna drink Kool-Aid, make sure it's not too watered down.
