Since I'm already pretty much settled down here in Aiki-Hell, I'll say that I personally don't care to do the founder's aikido. I'd rather find my own aikido.
The founder had wonderful aikido because he was doing what worked for him. He defined what "good aikido" was because he was the embodiment of "good aikido."
I take a look at the first generation uchideshi and such and see a wide variety of styles and approaches and believe them all good. Certainly, I can't do some of the very well, but they're all good interpretations through each person's body and minds.
As I've said before in another venue, I'm not training to become an "O-sensei clone" or a clone of anyone else. I'd rather find my own aikido.
