Ditto on the lower poundage in colder weather. Last year I took a doe on Dec. 15th and it was -13 I believe. I had went out for the last hour of daylight knowing that's when I had glassed them, no earlier in those temps. They don't like to get up more than they have to either in such cold. Anyway, my bow was set to 70 pounds and I about pulled my arm out of my socket to draw from the blind. And that was with drawing every now and then beforehand to make sure I was loose. I am thinking about getting a new bow after 7 this years and maybe going wiht a 50-60 for the extreme cold I sometimes hunt.
