Hi I live in Ephrata Washington. Wide open spaces. I need really good optics. I read last months article on the vortex razor spotter, the one with the results from field tests, the 15-45x65 is the one I am looking at purchasing, but it's a little out of my price range. I have been looking at the viper in similar size as an alternative. Would you recommend this spotter, or should I just save a bit more and go with the razor?
