So one can't resist using ki?
Yes, of course you can, I just feel that resistance is so easily focused on normal strength, it can make it so much harder to develop your ki/kokyu skills if resistance training if done prematurely.
I like what you are saying, I'd just drop the type B. It so hard to figure out one from the other the getting stuck somewhere in the middle is too easy.
Overall like your ideas, its just that resistance training too early can negate the chance to understand ki, I am fairly certain I have read before that O'sensei didn't allow resistance until third dan. But as a general guide to martial arts and aikido training I reckon that is a guide set of guidelines.
