I would adjust your site. It's too late for drastic changes with the rut underway. The whole reason we spend so much time fighting blazing sun, skeeters, bees, and snakes all summer at the range is so that when we punch our release at an animal it's a high percentage we kill it. That confidence won't let you down. Adjust the site, don't over think it now or you'll have doubts after you made your shot. In springtime though I'd run a walk back tune with field points and dial your broadheads in again.
