Much depends on the application wanted for your bino's. Are you hunting out west, glassing long distances, for long periods of time mostly in good daylight? Are you whitetail hunting the upper Midwest where you may mainly use your bino's when something catches your attention, at closer ranges and often in lower light?
While a 10x is often best for the former, it is not for the later.
If bowhunting for whitetails in the upper Midwest, I've found that the best bino's are the Leupold 6x32 Katmai's. Yes, 6x. At 6x32, they are very bright and very easy to orient a deer with, using only one hand, with the other holding the bow. They also give you all the magnification you need out to 250 yards or so.
If you use the system of determining low light brightness, you'll find that 32 divided by 6 offers more brightness than 42 divided by 8.
Sadly, convincing hunters that 6x is a great power for most eastern bowhunting situations is a hard sell and Leupold discontinued the 6x32 Katmai last year. You can still find them with a google search for $290, vs the old $450 retail.
If anyone wants what I think is the best eastern bowhunting binoc, I can't suggest them highly enough.
