For me at least, say for example, Kote Gaeshi, it is less about what you are doing to the wrist than it is using that as an access point to the spine...if you are doing it as an aiki exercise.
Yeah. I agree. For me, Kote gaeshi is not about twisting the wrist joint. It is about conquering Uke's centre & controlling his movement through the circular motion of his fore-arm. Not about the wrist.
