I had a cable issue with my Bear Instinct, for me it was the module..it didn't line up perfectly with where the cable rolls over on it, so it actually started clipping the edge of the cable.
The module needs to be a couple thousands wider or lined up better or something. It's made to fit flush against the cam but doesn't seem to be wide enough for the cable string to align perfectly.
I took the module out and super glued 3 paper punched pieces of paper to the side of the module beside each allen screw.
It was just enough to push it out just a hair so that the cable string lined up better with it when was drawn over the module and doesn't cut the side of the cable string.
Since I did that excessive string wear has stopped.
