I have a 2013 Martin Onza set for a 30.5 draw length. When the bow is set for this draw length (30.5) the cable impacts a rivet on the bottom cam, just prior to full draw and makes a clicking noise. Obviously if the cable hits this during the draw it hits it again during the release throwing off my shot. I took the bow to a well respected bow shop and they changed the cable slide .. no luck. The only way I can shoot the bow now is too shorten the draw length to around 29" which is just unsatisfactory. At 30.5 inches I am at the extreme most draw length for this bow.... still there should not be a problem. I get the feeling l there's a solution here other than shooting the bow at a shorter draw length ... which feels horrible as I am not at full draw. Working to find a Martin Authorized dealer ... wonder if you fokls had any suggestions.
