It all depends on your criteria. I hunt strictly monsters where every inch counts. So I would go 10x 42 or 8x42 something similar with a quality bino.Still give me a great exit pupil and and that higher mag will allow me to determine the size of the rack and points on the rack weather it be in the fields or in the woods alot easier cause it can be quite dark in the thick stuff especially around dawn and dusk and cloudy periods.Racks blend into the background very easily with branches infront and behind the animal it can hide very important information I need to know very quickly.I can very easily determine what I need to know about size.If size doesn't matter 8x32 in a quality bino.But I suggest you stick with 32 -42 size objective lens don't go with an objective any smaller, the lack of light will hinder the performance and make you wouder.Quality Binos are smaller more compact
alot lighter,than they once where, and are made with material that offer waterproof and shockproof.Glass is far superior now, and so is the quality of coatings on the glass.Binos are made better now a days, and bigger objective binos in alot of brands and models can be a huge advantage over smaller objective sizesin the same magnification, cause wieght and size are now longer factors.But
I suggest 8x32 10x 42 8x42 over anything else in a quality glass.
