10x42's are the "go to" bino for my wife and I for 90% of the hunting we do.. I carry a set of Leupold "Pro-Guide" BX4's and my wife has a set of Zeiss Conquest..
That said, I've been giving serious consideration to a small set (10x25? or something similar) of good binos (Swaro, Zeiss, etc).. the only "small" binos I have are a cheap, lower end set of leupolds that Ive had for almost 25 years and the clarity/crispness isn't there for my intended use..
Where we deer hunt, Ive only got maybe 200 yards of distance, and the shooting lane is less than 20 yards wide (not a very wide field of view at all) at my primary blind, and my wife primary blind sits on the edge of about an 80 yard deep, 40 yard wide field.. we don't necessarily need a big set of binos.. but it would be nice to have something small, light, and out of the way, to take closer looks at distance to see if that "doe" really is a doe.. or might have tiny buttons on its head... and its always fun to watch the smaller critters like cardinals, squirrels, rabbits, etc come into the field... sometimes working the 10x42's is a bit of a PIA..
