My Onza is starting to eat my cables. Cams are timed and the only thing I can come up with is cam lean may be excessive. Winners Choice Bowstrings maybe 6 mo. old. How can I eliminate as much cam lean as possible? This bow has been converted from the trg/sos and peaks out at 47lbs. Shooting a 380 grn. or 420 grn. arrow. Some help needed here, thanks.
