RE: PSE USA Spirit
Those Spirit bows are weird on the limb weights. Mine was a 50-60 pounder, but by the time I gave it away, I somehow had it drawing over 70# with the limbs bottomed out in the pockets. That's definitely one quirk about that bow that stands out in memory. Mine creaked on the draw after shooting it for a few years at weights that exceeded the limb ratings, which is why I had to upgrade. You could grease it up, and 3 shots later, she was creaking again.
Good hunting bow though. If your bro gets skunked this season, it won't be because of the bow.
