Agreed, I think smooth, crisp and reliable are much more important than lightweight when it comes to triggers. Spring weight is the last thing I experiment with after I have deburred and polished and trued up all mating surfaces. Less friction to overcome often allows slightly lighter springs to function properly. I have redone quite a few trigger jobs for friends who knew a 'guy' that thought a trigger job started and ended with swapping in 'lighter' springs. In the early 80's, when Jerry was beating us all with a revolver at our local matches, I asked him about reduced power springs. His reply was he wanted the strongest trigger return spring possible so the trigger reset could keep up with his trigger finger.
