So I bought a used Nitro 505 Veil Camo with 12 bolts, a pack of lighted Alfa nocks and the whole package. I looked over the whole bow with a magnified glass. It appears to be MINT! There's not even a ding on it, anywhere. The only thing I found is the string serving is worn, where the bolt hits. I want to buy a whole new string obviously . I'm sure most guys on here are going to say to buy a new TP brand string. I figured, I would ask anyways because it's seems like 1 season shouldn't wear a factory string like this? Has anyone used 60x brand or had better luck with a different brand? The bows used ,so its not warrantied anyways. I have a Nitro XRT as a back up, till I service this new bad boy. Let me know your 2 cents.
