Welcome to the wonderful world of speed bows. They eat targets plain and simple. I'm currently using the Rhinehart 18-1, so far I like it but its only 3 months old. I'm going to look into a spyderweb, have not had any luck with the Morrell bag targets, they don't even last a year. I've owned the Block, The Cube and The Black Hole and they are all a waste of money IMO.
