Thanks for that. So often any discussion quickly devolves into extremes instead of the real issue. I can't remember the last time I saw someone discussing a super light trigger for a defensive gun like 2 lbs. Hell I rarely see any discussion of trigger weights below 4-4.5 lbs. As you stated the differences are fairly narrow in band. Many of the people who seem to be most concerned and wound up by the minor differences don't have trigger pull gauges and/or don't realize or factor in the trigger's smoothness,pull length,where the take up and wall occur within the pull or stacking.
You last line isn't ambiguous at all. There really is no one size fits all solution. It is one of the few absolutes.
