Gents, I'm wanting to upgrade my optics, and for spotting scopes, I have pretty well decided on vortex, but not saying I couldn't be persuaded some other direction. My budget is around the $1000 mark give or take a couple hundred. This will be for hunting mainly, but also want to use it to film. So to my question. What do most of you think about the power. The Viper HD are what I'm looking at, and are 15-45 or close or 20-60. Which one would you go with and why? As always, thank you in advance.
