I have read quite a number of posts recommending the Vortex Viper PST Gen II scope. I'm sure that it is an excellent scope however, when I compare the PST 3-15x44 to my Vortex Strike Eagle 3-18x44 I don't see any advantage in trading up. The PST has less eye relief, max elevation and windage of 75 moa and 40 moa for windage compared to 120 moa for both elevation and windage on the Strike Eagle, .8 inches longer, and weighs 4.2 oz more. What am I missing?
