I bought these to have as a backup in case of an emergency during or close to hunting season. The packaging they came in did not have any identifying information so I hope they are the right ones. The original string on my new Recruit XP is already showing some serving separation on the cam area and center serving as well as wear on the center serving even though it is kept lubed which makes me question the quality of the string. I did not want to replace with an aftermarket string touted for quality materials and construction in case something happens during the bow warranty period.
