Last bow I purchased specified a 58" string , so I ordered a winners choice string in the same length . When I installed it my cams were way off had to do some serious twisting and untwisting to get it right . I measured the stock string which only had 5 shots on it , it was a 1/2 too long out of spec . So that is very true what Straight arrow is saying . After 3 years your string and cabel will be way off if they have never been twisted .
