The 8x56mm is the classic European low light scope. I think Schmidt & Bender has one model with a one inch diameter but the weight is not listed. A fixed scope has less elements so usually is clearer and brighter than a comparable variable and lighter. The Trijicon scopes looked good to me but have not used them in the field. Some of the Kahles were excellent in low light but were heavier due to the steel tubes. This can be said of most of the European Scopes.

The Leupold certainly wouldn't be a bad choice. Test them personally if you can as vision varies. In my comparisons the Conquest was closer to the Leupold VX-3 (older version) not the VX-2 as an example. Actually better in normal light but had a very slight blue cast that may have affected very low light clarity.
