A bow set at 65% letoff is a bit less inclined to torque than the same bow at higher letoff and, I think, is more consistently accurate because of that.

Frankly, I don't think it makes a bit of sense for a pro shop in a state with a legally mandated 65% letoff to be offering any bows in their shop at 80% (of course, I don't think any letoff over 65% makes a lick of sense anyway). The vast majority of their customers are going to be hunters and not strictly 3D'ers. I hope the shops inform their customers the bows are illegal for hunting until the letoff is changed?
