50# is plenty. Actually, 50-55# is probably about the average draw weight of traditional hunting bows. Alot of guys hunt with less. I hunt with 60-65# straight limbed selfbows that throw an arrow slower than some 50-55# recurves (about 150-160 fps). I know one fella who shot clean through a doe with a 32# selfbow. That arrow was probably only going about 120 fps. Place your shot carefully and you'll do fine.
