I am most impressed with your body's ability to handle the cold b-b. Golf gloves on sub-zero temps is impressive to me. My fingers (and toes) must not have the circulation to handle cold, never have. I am done bird hunting in single digits and below, there will be better days for me and them. Watch those ears, you don't want to look like a North Dakota calf born on a cold February night. I know you really think the hearing is maybe even more important that sight, I would strongly disagree in my hunting with only a single dog. If I were completely deaf, I wouldn't miss many shooting opportunities, as most flushes are near the dog which has my entire focus...guessing the same with you, but your multiple dogs makes it difficult to be in close shooting range of flushes by both dogs and hearing a flush from the dog you don't happen to be watching at that moment, gives you time to react and make that shot, I get that. Still, you can't shoot them if you can't see them.
