Hi guys. I am in the market for a pair of binos. I know the Diamondback are argon filled which is better than the nitrogen of Crossfire. But with the warranty and customer service this should not matter right? The Diamondbacks have a larger FOV. But they weigh a little more. Have any of you used both and would recommend on over they other? Why? FYI: I was looking at Nikon Prostaff 7. But the Vortex transferable warranty no questions asked and CS sounds top notch. Thoughts? Thanks
