I'm so Deakin frustrated, I thought my string was strectching , but whenever I tie my know, like I said I tie it about 2 inches from the nock I struggle to bed Tue bow to get the knot up to the nock, it gets the strong taught and I thought it was just still streching once I got it off the tree but the knot is just righting up around the nock Leaving like 4" slack and I just xnt know how to fix it
