If you do a lot of dedicated open country hunts then you probably have or will eventually want a high powered spotting scope or bins (i.e., 15x56, etc) anyway.
I personally have Nikon EDG 10x32. They have the FOV of most 42mm objective bins out there but even still I can see how they would feel a bait more steady if they were 8x. I just couldn't pass 'em up for $600.
