FWIW, It's a mistake to limit MMA discussions to MMAsport-not my interest at all. MMA as a study -has introgued and involved tradional guys from way back-and was the precurser to the modern MMA sport stuff. They are not the same.
Agreed...Most really good Martial Artists did not limit themselves to thier Kata and in fact tried to improve upon what they were taught.
Which is why I look forward to seeing you in August and I am sure if Shoji Nishio Shihan were still alive he may have ended up incorporating Aunkai (sorry Spelling escapes me) Kata or more Aiki exercises...IOW "Kokyu Power" in Aikido separates the men from the boys...Whenever I feel someone with such skills it makes me realize how much more I have to learn and experiance. Even up to the point he retired from active teaching Nishio Shihan was always looking for ways to make Aikido better and a more complete (hence effective) Budo.
We are all MMA.
