You should shoot whatever your comfortable shooting if your hitting where your aiming. I shot at 70 lbs for years but I am shooting now a little less poundage because of an elbow that has been troubling me and shooting at 70 lbs just isn't comfortable for me anymore. I guarantee you if shooting at 70lbs gives you trouble at the range it will be a load for you in a tree stand with a bunch of clothes on. I don't think you should shoot under what your capable of shooting accurately and comfortably though so I can't agree with the guy who told you there is never a need to have your bow over 50 pounds. 50 pounds may be perfect for him but not for a lot of others.
