Re: Scope advice
From what you are describing, a lighter, mid-power range scope is what you are looking for. It used to be that Leupold ruled the roost in this area, with great glass, light weight scopes. Newcomers include the higher end of the Vortex line and the Sightron SIII 3.5-10x44. Anyone of these would fit your purpose. Quality of glass is largely determined by personal preference, so trust your own eyes and give that more weight than the opinions of others.
I can't speak to thew Zeiss or Leica optiona as I have never owned either. I currently have a Nightforce on my LRH rig. The Nightforce line of scopes are great, but they tend to be over-engineered for heavy/tactical/combat use. As such, you would probably find them too heavy and a bit bulky for your application.
