Hm, no specific "tricks". Very "normal".
Not breaking ukes elbow but locking it (compare hiji kime osae), so bringing strain (?) to his arm and by this creating a connection to ukes center.
Throwing in the direction of uke, not forward.
I emphasize very much on the rotation of toris arm which lies under ukes elbow. This seems most important to me.
No leg sweeping or something like that. Not hitting ukes elbow.
Just "normal" waza.
I just found this video.
(But it's a little bit "show".)
In each of the points you make I would generally agree on .These are fine in a dojo, but within the context of the original post I think you might have to modify the waza to suit the uncompromising Uke.
