is it showing wear? is your bow in spec still? has your peep been rotating on you? No, yes, no are your answers then your good. I usually just replace mine every 2 years because I shoot a lot and I do the work myself so I am only out 80 bucks to make sure everything is good to go. I had a buddy that waited to long and his string was stretched and wore pretty bad and wellllll he needed new limbs, limb pockets, cams, and string after she blew.I'm 3 years on the strings on my Reign 6, is it time I got new also?
