I'm sorry, but Crutch, reading your reply is like finding the miracle bow. If you've shot a bunch as you say for 6 or 7 years and don't think your string has stretched, whoa nellie, it's beauty. The other though is, your bow is so far out of tune after 6 or 7 years from shooting the original strings you don't know what you're missing. ALL factory strings stretch... some more than others. Usually they're pretty well settled in after a couple hundred arrows. Bowtech happens to have one of the better factory strings. Frankly, there are some expensive bows sold that have crap on them. I also can't believe a ProShop would tell you to keep that 6 or 7 year old string on there. It's way past due for a change if you shoot just a moderate amount.
