For me, locks should include throws,
The way I see it is that throws are harder to execute properly, consistently, against a variety of different body masses.
The pins seem easier and quite effective in themselves.
Ikkyo, ninkkyo, etc. - my favorite is sankyo...
Pain compliance - if that doesnt work, follow it up or start with some heavy atemi.
For non-violence one can walk away...and the situation wont arise.
Until then the above isnt that bad.
the only one in the 'throw category' I like is kotegaishi.
(though thats like a pin of the wrist.) Though I like shihonage as well. But that has a nice twist of the arm in it, etc.
Least favorite is iriminage, but I see its merit if you can master the various techniques of it...quite effective.
