I have a martin cougar III (3) with the older model fuzion cams and magnum limbs the string length is 86 1/2''. The string is begining to fray around the cams and kinda coming apart down near the bottom cam. I got it last summer brand new at keystone country store. It was on sale because it wasnt sold from the year before. So it has to be a 1 and a half to two years old. Just getting into bowhunting i never waxed the string, I used it for one season. I shoot alot so i want to get a good string that will last and now that i know, i will wax the new string to prolong its life. What would be a good high quality string for me to get? Any advice would be greatly appreciated.
