I have a 2001 Cougar 2000 with Zcams, and I'm trying to get it shooting well with fingers...the label on the bow says the letoff is "hi"... I assume that is the 75%... how do I change it to 65%? Do I need to find different modules, and do you think that changing will make the bow more "finger friendly"? Also, it appears that the cable guard can be mounted either above or below the grip (it came mounted above)... what are the ramifications of moving it? Forgive me if these are silly questions, I really appreciate the help!
