I have been using a Leica 2.5-15x56 which I find just about perfect for the hill. 30mm tube, not too heavy. Ret in 2nd FP with daylight bright illumination. Adjustment on elevation but not on windage. Low power for close shots (have used down to 4x for close shots) and 15 for long. 56 Obj nice for a bright image on grey days or if you end up in forestry. Forgiving eye box for awkward shooting positions and parallax adjustment.
