Best Size Optics for Backcountry?

For most situations the 10x42 would be the best bang for your buck, the only other option in my oppinion would be if you are in heavy timber a lot or doing alot of sheep and Mt. goat hunting and want to go light, then I would go with an 8x32 or 10x32. I use the swaro's also

There is a lot of info here....we use 50mm objective stuff here on "bean field" hunts and that is what I have always carried to the praries, so i knew that my existing optics are out.

Gonna pick up 10X 42ish (probably zen ray ED)

Now on to the spotting scope.

Thanks for all the info!!
