BM,
Just a thought, but when I set my MM up I took the slide of and the cables naturally crossed above the cable gaurd ,but when I got the bow they were set up crossing below it, I put a Bomar slide on it and put it on with the cables crossing above and haven't had any problems, and what a diff. with cable wear w the bomar on it, I don't know if you will actually gain any room w the Liberty but it might be worth a look.
