I've heard good things about the BX, though I haven't tried it.Good point... I was thinking an out of box Ruger BX-Trigger, but I'm not sure it's compatible with the Midwest chassis.
I've got a Kidd 2-stage, stock, and stock with Kidd upgrade kit. I semi reviewed that kit here: https://www.northwestfirearms.com/threads/build-up-10-22.318516/
I'm very happy with how it turned out…for a single stage trigger, I'd go with it every time.
