Bigt, I cut the ends of my spray bars off and put a pvc ball valve on the end of all 4 spray bars. That way when they plug you can open the ball valve on each end and blow the trash out. I tried opening my holes up but we fish in alot of matted grass, and sylvania, and duck seed and I was catching fits. This seemed to help alot. Take care now.Chris CoupelPaulina, La.Chris CoupelPaulina, La.
