If you can point your arrow at a target and draw it stright back without a big bump at the end of your draw cycle, I would say your fine.
I agree with this....WHATEVER your poundage.
Drawing in "cold" weather is a factor. I was pulling 71#'s in '06 when I arrowed my 8-pointer....after being on stand for more than 4 hours in the "cold". If you can.....you can. Don't worry what others think.
