RE: Bow question ????
I had this issue with my Fred Bear Instinct. If your string is 'stretching' that's one thing. If it's getting 'cut' or 'chewed' that's another and there is a reason why this is happening.
Make sure the cam and module are perfectly aligned where the cable string rolls over where the cam/module meetand not slightly misaligned(I had this problem)If in perfect alignmentthena new custom string shouldwill solve your issue. If not, well.....I placed an extremely thin shim(paper&super glue)between the module and cam and it solved the issue of the module 'clipping' the edge of my cable. Worked for me anyway.
As for what Flybub mentioned with the dremel, I elected not to mess with taking a dremel to the module or cam once I put them in perfect alignment as excessive wear stopped.
