Any scope should be strong enough to be used as a carrying handle. Optics need to be clear. I prefer simple reticles and don't need or want rows of hash marks or dots. I prefer a scope which is small enough that the scope won't be the first thing which hits the ground so no 50mm objective bells. Weight is not a huge consideration but bulk is, to me. I carry the rifle in my hand when I am backpacking and a bulky scope doesn't make it carry better.
I am perfectly happy with fixed power scopes of 3X or 4X but I understand that most modern hunters are not. The perception is that one can not hit anything beyond 200 yards when looking through a 3x scope which is simply not true. In the end, it's a personal choice and, I'll confess, if SWFA would make a scope with a simple reticle and a little less bulk, I'd buy one. GD
