Greg, I use a gloves almost all the time when I hunt. Bow hand gets a full glove, string hand gets a glove with the 3 middle fingers cut off half way. I use a superglove and slip the glove right over it so the three leather fingers are exposed.
As it get colder, I add a hand warmer in each pocket. The big ones when it's real cold.
I always try to hang my bow as conveinent as possible so I can keep my hands as long as possible in my pockets. When the time comes to grab my bow, I grab it, and get my string hand right back in my pocket grasping the warmer if the shot isn't happeneing just yet.
When the time comes I take it out and do the deed. If it doesn't happen quick, I try to get my hand back in...the key for me is to keep the warmer in my hand, in my pocket as close as possible to the shot.
I'll also go to a slightly heavier set of gloves as it gets real cold.
I know what you mean about hands not working well when cold...it's always a battle for me too...cold finger just don't work well!
