How does the 6x42 compare? I have my eye on that one for an old pre-64 Mdl 70 for pronghorn hunting. I'm torn between the simplicity and classic style versus spending a lot more for the best optics. I won't dial on this rifle, so all I care about are the optics. It's sort of a strange dilemma because I'll either like the FX3 better than anything or I'll end up spending a lot more for a S+B Klassik or Swarovski variable and making it "un-American."
