I prefer to not use gloves but it beats losing all feeling in your hands. Then you are really going to shoot poorly! I like thin ones. I have got a fleece pair that is very warm and has rubberized grips on the palm. They are really nice for shooting the bow. Before those I was just using those thin cotton ones. They did not help all that much.
I wear a glove on my hand that holds the bow, but for my trigger finger hand, i tend to just keep it in my pocket to keep it warm. When it gets really cold I stick one or two hand warmers in the pocket. It works to keep it warm, but allows me to keep it ungloved. Not only do I like it for the trigger finger, but it helps me to feel my anchor point too.
Hunting is not usually a pursuit where instant gratification abounds. It takes a lot of time, practice, resources and patience to be a successful hunter. So when someone decides that an area they hunted only once without taking an animal is worthless and devoid of game, I don't quite understand it. These people usually jump from game management unit to game management unit; trying a new one every year.
Now don't get me wrong, there are people that just enjoy scouting and hunting...
