Out of the Zeiss lineup I would go with a 3-9x40 or 3.5-10x44 take your pick, still shaking my head at why they needed to bring out 50 and 56mm scopes. Nikon gold is a tremendous scope but the lightest(1.5-6x42) is 17 ounces and that weight goes up to about 24-25 in the higher powers and not to mention the 30mm tube. Not extra weight I need to lug around all day.
