Here are two simple (I hope) questions:
I am studying Yoshinkan. We are learning nikajo like this:

We are told that nikajo should not be painful in the wrist. This is a difficult effect to produce, but as uke, I have felt times when the only thing I noticed was my hip and knee collapsing--no pain response.
In the past I have felt budoka from different martial arts trying to apply this technique--nikyo, I believe, in Aikikai. I always thought it was supposed to hurt at the wrist, and the problems people always had were in avoiding collapsing the arm.
Does Aikikai try to produce pain at the wrist?
And, in learning Aikikai's nikyo, is collapsing the arm into the body rather producing an effect on uke a problem for students?
Or, in Aikikai, what is the main hurtle for students in learning nikyo?
