I'm looking to upgrade from my Nikon Monarch 5's. I currently have the 10x42 model. I'm looking at the Vortex Razor HD's 10x42 or possibly 8x42. Do you think I'll see a noticeable difference in these in real world applications? Kinda hard to tell at the store. I'm also considering the Zeiss Conquest. The Razors are lighter and I like the Vortex warranty, customer service and veteran support. I'll be using these mostly on western hunts spending long periods of time behind the glass.
