My bow is squeaking while drawing w/ an arrow nocked. It doesn't do this drawing without an arrow nocked. But I am trying to pinpoint the location of the squeak. Logically I would think it is the rest. But I almost swear it is not. It sounds like my cable guard is rubbing, but would that make a difference with or without an arrownocked. Ive checked my rest and it looks fine, its a quick tune and the rubber sleeves are not worn at all. I have pushed it down and there is no noise at all. any suggestions
