My buddy put them on his arrows. He would use a blow dryer to fix them. He did that maybe six times anf then they wouldn't bounce back anymore. He stopped using the quick spins after that. I had the same problem where I was getting pass through shots. I just became a more accurate shot not to hit the middle where the two bales of straw met. It made me mad that the county tied two together in stead of getting a bigger bale.
