I agree Peter, extremes either place one's mind in a box, or makes it so etheric that there is no substance to make meaningful decisions from.
BTW, did you ever read the book written by Scott Allbright from Shodokan UK - Aikido and Randori I think was the title. A great complement to the Nariyama/Shishida book.
Chuck, I too am still looking and searching... will let you guys know if I find anything
If I get lost you'll find me on your dojo step
