.. may I say due to the differences in posture between judo/aikido
the kuzushi may not always apply? Aikido posture means instability from a push /pull from//to the side.Judo weakness is a push /pull to the back/front due to shizentai posture .The two postures in my opinion are imo incompatible....
If anybody expresses doubt to me about Kamae, I generally go into a wrestler's crouch and show how similar it is. Shinzentai and Kamae are not that different, either. But many other Aikido styles don't use it, so YMMV.
