10x50 - FOV 390@1000, Exit Pupil 5.2mm, weight 36oz

To me it is a no brainer the 10x42 is the best combination of attributes for use when hunting.
Personally I went with the Zeiss 10x40 SFLs 377@1000, EP 4.0mm, 22.6oz. The Pures are nominally better glass. However for me the weight difference more than makes up for it. Plus with the price difference you have a good chunk of a quality spotter paid for if you have a need.
