@Grady. Yes, I was very sad to hear about Sugano-shihan. Although I have heard that Aikikai Australia can be sticklers for their rules, I have only ever heard good things about Sugano-shihan himself.
@Diane. Thanks for the advice. I will actually not be too far away from Tony, so it shouldn't be too hard to have a chat with him. I will also check out all the dojos in my area and see which one seems to meet my needs the best. Of all of the senseis in the area, the only one that I haven't met is the Aikikai Australia one, so that dojo is a bit of an unknown quantity to me.
I have known Tony Smibert for many years and have frequent contact with him. If you want any help, you can send me a PM in complete confidence. Or you can use the e-mail address given on the IAF website (aikido-international.org)
