well, i went to matthews and saw they offer a limited lifetime, so the arm (limb), may be covered but my season may still be shot. I'm still interested in some feedback to the original post, but additionally, where is the serial number. I've been looking over the bow and can't find the number. I remember registering it when new but sure can't find the numbers at this point. It is a 2000-2004 series bow. thx
