This is a good discussion.
I think that another common bond between Tomiki and Mochizuki is their belief in various types of randori and competition for the benefit of learning. In my experience there is a large gap between paired kata training with varied levels of resistance and even shite randori. And then yet another gap from shite to jiyu randori. In my (limited) opinion, training with increasing levels of resistance combined with increasing levels of uncertainty during randori, steadily bring it all together while maintaining fundamentals.
Thank the heavens and Judo's influence for randori.
I have no experience with the Aikido you mention above (Tomiki and Mochizuki), but I agree, and yes, thank the heavens for Judo's influence!
