I like zombies.

Anyway, you like shihan B's seminar teaching style and his aikido. Great. I would suggest looking at shihan B not as a seminar teacher, but just as sensei B. That's to say, are you certain that the aikido and instruction you experience at a seminar from this person is indicative of the organization's aikido and pedagogy, the shihan's seminar specific behavior, or of the person's day to day teaching skill? Finding a org B dojo may not help. Finding shihan B's dojo may help.

Sounds like you have too small and limited a sample size on the one side to jump ship. Kinda like wanting to move to wherever you just went for vacation. Life (on vacation) is great in Vegas......
