I cut weight in a lot of places and do without several things many folks here consider "essential", but not just so that I can add weight in other places. The weight cost/benefit ratio depends on a lot of things: personal preferences being hugely important..

I have no issue with a SWFA 6X on my Kimber Montana .223 Rem for backpack hunts, but lightening things up always crosses my mind. I just am not willing to sacifice scope reliability and confidence to save weight in said scope. I sometimes go without fire starter, and even without a tent/sleeping bag on shorter, good weather hunts to lighten up. Sometimes I regret it, sometimes I don't but I don't regret bringing a heavier scope if it is what I am confident with.
