I have a Martin Cougar bow that was custom made with SE limbs to accomodate my short draw length (24" draw). In the 2 seasons that I've owned this bow, it has blown apart on me twice. The limbs and parts are all fine, my concern lies in the string breaking. Both times the bow came apart, it was the string that broke. It broke right where the string loops around the small posts on the cam. I should also mention that I have the Nitrous cams on the bow. The first time it broke (2 weeks before the 2005 bow season)I had no idea what could have caused the string to wear so much in that spot, other than it seemed that the cams were somewhat "sharp" as if they had not been machined properly on the edges. The 2nd time it came apart was the afternoon before bow season opens. Imagine how upset I was. Regardless, the string broke in the exact same spot. This time on both ends of the bow. Since then I've sent the bow back, had the string replaced again and I believe Martin replaced the cams..they seem smoother and more "machined" this time. I'm looking for an opinion basically. I'm worried that the thing is going to come apart on me once again and am wondering if there's a possibility that my custom setup is the reason behind the string breaking. Like I said, I have a 24" draw, I shoot 47 pounds of draw weight and I checked the owner's manual and my arrow length is satisfactory for my setup. Any ideas out there?
