Another tip.

I wear those snug fitting knit gloves you can buy at most grocery stores for a couple bucks per pair. I hate not being able to feel the trigger of my release, and i really dislike cutting the index finger out of pairs of gloves.

If you buy a hang muff that hands around your waist, put a couple chemical hand warmers in it, and wear those thin knit gloves your hands will stay plenty warm and you'll be able to feel the trigger of your release.
