Having met and worked briefly with Sensei Quackenbush when He dropped by our old dojo years ago I can say from both his ukemi with me and mine with him that he is a very thoughtful Aikido practitioner with serious intent. So Sensei Quackenbush I found your posts very insightful.
In short I agree with your Aikido is only as good as your "intention" as Uke.
At least that is my experiance.
