The vxII 4x12 with a fine duplex would not be a bad choice. They are not that big and clunky. I have a vxIII 2.5x8 BC on my jackson squirrel rifle and can shoot very good groups with it. The BC ret. has pretty fine aiming points. and works just right at 7 power for 75 and 100 yds. with a 50 yd. sight in.
