I've seen a lot of good plans and superb optics end up staying in camp after a couple of days of trying to lug a heavy spotting scope around the mountains, so I'd recommend keeping the weight down for a hunting scope when you can. Even an optically inferior one in your pack will be better than the $3k model in camp. I have a big Razor for the range, a 60mm Swaro for most hunting, but keep looking at the little Vortex because I know that it would always be with me. Also, weight be damned if you need superior optics to help ensure that an animal is legal; buying the scope will be cheaper in the long run than paying the fine for a sub-legal ram or moose.
