You can get complete passthru with low poundage bows by going for the ribs. If you are afraid your accuracy isn't enough to keep the arrow in the ribs, you can go to a higher poundage bow. Just be bloody dang sure you don't blow your accuracy even worse. I shoot a 50# bow regularly, and practice with a 60 lb bow from time to time. I just can't hit the side of a phone booth from the inside with the 60 # bow!!!
