For West Texas the 10x is my preference. If you are in the habit of using a shooting stick, tri-pod or a rest most of the time the 10x help in open country. Without a rest the 10x picks up my shaky hold enough to make it hard to get a reading where at 7-8x I can usually get a reading free hand or by putting tension on the strap to steady the range finder. My experience is with a separate 10x40 Leica and rangefinder I think the 2,000 model.
The Geovid is nice in eliminating two items around your neck and the added movement to shift between them. In really cold situations I keep the binos inside my jacket to reduce fogging, might help with the range finder.
"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
