I can put up with a heavier trigger if it breaks like glass, but I don't like them over 3lbs, and I like some a lot lighter like on varmint rifles, as others have stated.
One thing that makes a lot of difference to me on how light I want a trigger is how wide the trigger is. I find that I like skinny triggers a lot lighter than wide ones. A wider trigger feels noticeably lighter to me, even when the scale says it may be set the same or even a little heavier than a skinny one.
I am getting used to the dramatic curve in my Kimber trigger. It is unique in my experience, and I am liking it pretty fine.
