On reflection I'm changing my vote from "no" to "yes." Part of the reason for switching is I realized that being around people of character is important to me. I would choose a dojo of good character and less than perfect aikido over one where flawless technical execution is attained by people of poor character.
The outward signs of character can be observed. Clark sensei provided a good starting point for a list of traits and, much like the technical parts of aikido, you could hold mudansha and juniors to higher and higher standards as they progress up the grades. The yudansha must be of excellent character.
ps: The aikiweb computer does not allow people to change their vote. Y'all will need to shift one of the nays to aye when looking at the graph.
