I bought by jennings new last may and have been shooting it pretty regulary. In July I am going on a big hunt so I was thinking about putting on a new string. When do you change the string? Should I change mine? It looks good but how long do strings last? Also, if I put on a new string now will it stretch over the next few months changing my draw weight and site? What would you do? Any suggestions on strings would be helpful, Thanks
