I was just reading through your post. I hope you don't think that Kit and I think aikido type training is not a valid form of training. As obviously the Japanese feel it is worthwile.
This is true, and why I wanted to avoid that impression. HOW you do something is more important than the something you do.
I have been favorably impressed by some people's application of aikido or aikido-like strategies and techniques. I have seen others that were no so impressive. I have seen some excellent BJJ based combatives stuff offered, and some very poor examples.
