i am shooting a titan off the shelf with black max carbon extreme limbs. i have arrows bare shaft tuned (bare shaft flying perfect and within same group as fletched to 30 yds). when i shoot a cavalier elite tab w/ super leather, i shoot nice groups at 30 yards about 6-7 inches to the left. when i shoot my bateman cordovan leather tab i shoot 4-5 inches to the right. i tuned the bow to different center shot locations with similar results. any suggestions would be appreciated.
