Winner's Choice strings and cables are known world wide as the most stable, longest lasting bowstrings in the industry. Each string is built using a proprietary process that pre-stretches the string fibers before assembly, and the patented serving system and exclusive serving materials insure consistent results. Winner's Choice strings are guaranteed against serving separation, peep rotation, and excessive creep for 1 year. Also, Xcoat wear reduction coating where applicable protects strings from abrasion wear in the cable slide area. More pro shooters trust Winner's Choice than any other brand.
