I hadn't had any issues withthe prestretched/ no creepwinner's choice string thathad on my Xtec. Bow shot the same from day one for two years withalmost daily shooting. Never went back to the shop for anything.The fuse string too is suppossed to be prestretched /no creep on my Trykon. The Trykon has had at least 1000 arrows through it with no adjustments. I hope my factory Bowtech string lives up to this quality too. I suppose that if you shoot crappy strings than this is an issue.
