I never paper tuned. I shoot broadheads and fieldpoints together at 20 and 30 yards to make sure they have the same point of impact and practice with broadheads at various ranges. I figure if my arrows hit what I'm aiming at without having to adjust for the type of point I'm using, I'm good to go. Maybe I could gain a little efficiency if I tweaked everything into perfect tune and jupiter was in alignment with saturn, but I'm happy if my broadheads and fieldpoints hit the same place.
