I'm looking at upgrading spotting scopes and was wanting some opinions on objective lens sizes. Main use will be fly in hunts. I have been doing some homework and I'm leaning towards either a Vortex Razor in either 15x45x65 or 20x60x85 or the Meopta s2 30x60x82. Swaros are nice just a little to expensive currently. Any thoughts/advice would be greatly appreciated.
