it's possible for somebody to have good aiki skills, but still need to work on the jujutsu, I suppose.
I'm not convinced that you can have aiki and not have done the jujutsu work first.
I think that people have to train enough jujutsu to udnerstand when they are confronted by something that's just different. Does not fit in the pardigm.
I don't think that most people hwo have not done the jujutsu get it.
