Re: Recommend good DVDs?
Stop me if I'm wrong, but are all demos pre-arranged? I have never participated in one that has been pre-aranged, and in fact I find it rather odd to do so.
As for DVD's, I found the Mustard sensei and Chida sensei DVD's released by the Sendokan dojo in Canada to be infinitely helpful in understanding the logic behind individual techniques (riai) and I return to them often during my training.
The Yoshinkan Honbu released a series of tapes/DVD's that explain the kihon for nearly every kihon waza...probably not too interesting to many of the aikikai people out there, but the explanations of the techniques have merit in all styles of aikido because of their similarities/crossovers.
