Parker Stealth Hunter set at 66lbs 30" draw. I use to pull 80lbs but my shoulders just couldn't take it anymore. I think the only difference in the 80 and the 66 is how deep the shaft sticks in the dirt after a pass through on a deer. I'm sure there's more KE from the 80lbs but the 66lb is plenty of me and doesn't hurt my shoulders to pull it.
