I personally am a Leupold fan. Quality optics and they have been one of the few optics that I haven't had fog/waterproof issues with. I put them through the works tossed around in the truck, dropping them here and there, etc. I go for the 10x50's as it helps gather light for early morning spotting before light. I spot and stalk so prefer more long distance binos going after Mulies and elk. Have had side by side comparisons in the field with Burris and Nikons and we end up passing my Leupolds back and forth to everyone in the group.
