Leatham said something at Shot Show about not being able to handle a 3#+ trigger very well (I'm sure that's relative) because of all his years shooting lighter triggers.
I would be interesting to find out what the top 20 shooters prefer on a trigger.
I'll bet there will be a strong correlation between their answers and the way they control the trigger. Trigger slappers like Leatham will, in my prediction, want lighter with minimal pretravel. Feeling the reset is not an issue since their finger is not in contact with the trigger when it resets.
People who ride the trigger will want a heavier pull so they they can feel the reset.
