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!!
