I have used 10x42's almost exclusively for the last 20 years.
Have some 8x30's that went by the wayside. They might get used more since they sit by the window for looking at critters in the backyard or across the gulch. But not in hunting situations.
Had a pair of 15's that I sold, the 10's do just as good for locating criiters. If I need more than 10x, 15 is not enough. I go to the spotter.
That is what I have found works for me from the prairie to the Black Hills, Florida to Alaska, and Africa for good measure.
