I voted 31-40 yards but it depends on how much I have been practicing. This year I haven't had as much time to practice so I would not take as far a shot as I normally would. This year 30 is as far I would shoot unless I can get enough time in to feel confident at 45 yards or so and then I would still only take a 40 yard shot. I try to shoot slightly less than my MAX capability. I hate losing deer and this has helped me cut my recover/loss ratio.
