Like Dan said all good,never had a string that wasn,t accurate . only thing I found is the factory strings seem to stretch much more than the custom made ones . I shot many factory strings ,had great accuracy but never seemed to stop stretching .as long as I kept the brace height the same,no problem with poi,but servings come apart quite often. If you have a string from one of our fine string makers on here using one of there prefered materials you are set or just make a quailty one of your own,you are good to go . I would worry more about other things than the string for accuracy.only so much a string can do. there,s other things you can do to improve your bow, like,ARROWS, string hitting your serving in the center,string down pressure on the rail ,brace height,bow tiller,trigger an a few more I forgot I,m sure.there,s a big difference in good broadhead accuracy an great broadhead accuracy. plenty to tinker with ,an don,t believe it when you hear you can,t tune a crossbow.
