Which model 70?
The pre-2008 rifles have a very simple, rugged, dependable trigger, but from the factory they are often not the smoothest or lightest. Once worked on by someone who knows what they are doing they can be as good as needed on a hunting rifle. Personally I'd not give up the rugged foolproof design.
The FN made rifles since 2008 have a different trigger. It is typically much better from the factory and can be adjusted down to around 3 lbs which is as light as I want on a hunting rifle. I know some guys who want to go lower than 3 lbs that have replaced them, but I don't see the need.
