I used to shoot my bow at 65 lbs. Never had a problem, till I sat is a stand perfectly still for 4 hours in very cold weather, and had a nice 6 pointer walk up 15 yards away. Needless to say, due to cold stiff muscles, I couldn't get the bow back without struggling enough for the deer to see me and bolt. Now I shoot 2 bows, a Jennings CarbonMaster Extreme, at 51 lbs., and a PSE Baby-G Force at 55 lbs. I found dropping about 10 lbs. from the weight I could comfortably draw under ideal warm conditions, eliminated the problem of being able to draw back with cold stiff muscles, and I'm not shooting any fewer deer because of it either.
