Re: 10 or 12 power binos?
I am not sure of the brand you mention, but I have an older 14+ year old pair of 10 x40 Zeiss that are war horses! I love them! I got a pair of 12x50 Leica binos a few years ago that are great when you have some big country glassing to do but you need to wear them in your armpit or they bounce off the saddle horn all day, and they flat wear out a Bino-buddy every year! The damn things have a very finicky eye to eye focus adjustment and I am constantly screwing with the focus! I wish that I had the Swarovski 12x50.
Ya gotta be tough when yer dumb!
