I'm really surprised you rate the Leupold 1200 so high. A good friend and elk hunting buddy is on his 3rd unit. Good warranty/CS, but not a great product. At least in his experience. Shows how mileage varies I guess.
I was out deer hunting with another buddy a few weeks back. Sunny, clear, cold, approx. -20C. His Geovids were struggling to range anything. My 2700b was performing well. But I carry mine in a cargo pocket. His Bino was on a harness, outside all his layers. Maybe it was just body heat making the difference?
Form seems to think highly of the Nikons. Maybe give one a try and let us know how it goes.
