Re: Ki, Aiki, Aikido. The 'internal stuff' that never left Aikido
I'd also add to this one by Mark that concerning Akuzawa. I've been watching the youtube vids of him whilst eating my lunch. They are essentially equivalent to ki-soc exercises (no surprise there then nwhen you consider lineages and all that). They are just using and practicing these skills in a different environment with different emphasis. Ki Society dojo and those related to that family of aikido should be able to teach you these things. They also teach them as separate ki classes so you would have no need to practice aikido waza to 'get it' if you don't like aikido waza. You can always use them in your preferred MA in any way you see fit.
