I have had this Bowtech justice and the same W/B on it now for about four or five yrs. I notice in the past few weeks that my shot groups have been getting worse? I tryed everything then i noticed my w/b disc is really worn down and when i pull back to full draw my arrow sinks down further than it should through the black fibers causing me to get all kinds of different kinds of arrow flight?.

Has anyone ever seen this before? And if so what do i need to do just replace the disc?
