Crisp break, is about the most important thing for me, since our rules said we had to have 4.5 pound minimum triggers meaning we ran closer to 5 so we would never fail a weight check.
I've yet to pull a single stage AR trigger that I like.
But as I've noted, its all so personal.
You simply are leading a very sheltered life, then.
The best single stage triggers like the Elftmann Match & the Rise 535 are everything that you are saying you want in a trigger except that they are not 2-stage.
............and they will be dead solid crisp with zero creep.
