If you can afford it, having two pair binoculars, 8x32 and 10x42 in my case (and 15x56) are a great option, just like having multiple choices in boots, coats, pants, etc. I find myself grabbing whichever pair makes the most sense for the hunt I am going on. To explain further, the 10x42 always go sheep hunting (see forever, horn curl and age restrictions), caribou hunting (antler point restrictions), etc. The 8x32 are my choice for tighter cover elk hunting, most whitetail hunting from tree stands unless you can see forever into the ag lands, moose calling, hiking around the house, etc. The 8x32 are a joy to carry...the 10x42s not so much. If mainly carrying them in the vehicle or quad size and weight doesn't matter much. Light gathering has always been satisfactory for me with either the 8x32 or 10x42 (both with a twilight factor of 4....never thought I needed brighter binos than that for where I bowhunt) Decide which traits are most important to you for what you use your binos for. Pick one and be happy!
