Just saw GPO come up on Guidefitter and saw they had the new Rangeguide 10x50, the question is how does the glass in this new rangefinding binocular stack up to say Leica HD-Bs? I know GPO is founded by the Zeiss Sport Optics guy but not sure how their products fair against the big 3 (Zeiss, Swarovski and Leica). They have an interesting lineup.
