I've used Timney and Triggertech, both with great results. Triggertech Special two-stage flat trigger is my favorite trigger, period.
Why the 2 stage flat? I was thinking flat for a single stage so that it is completely different from anything else I shoot (milsurps) and curved if I go with a 2 stage because all my 2 stage milsurp triggers are curved and it would be a familiar feel just lighter. My K11 and 1903 Springfield have quite good triggers for milsurps.
