Agree with Big Uncle. The 15X-56 mm Swarovskis will be heafty. And that high a power and unsteadiness on your part will be somewhat frustrating. Wiht a steady rest, these would be great for long range viewing.

I would think for general hunting 8X-50mm or 10X-50mm , 40 mm would be plenty. I prefer 10X-40mm.
