Picked these up yesterday: I compared them side by side with the Vortex Vipers..........The 7's seemed to be the better piece of glass to me. 7's were clearer, and seemed to 'pop' more when viewing the same object with both sets of glasses. The 7's were noticeably lighter and felt better in the hand than the vipers did to ME......the Viperes were good, but the 7's just felt better to me in the hand. So I picked these up. I will try to post back as I spend some time behind them and what my thoughts are about them.
