LineJammer-SS, the best-spined shaft in its class, gets even stronger and better in 2008 with the addition of our exclusive Built-in Weight Forward™ technology. Built-in Weight Forward significantly improves down-range accuracy by helping the LineJammer-SS recover faster out of the bow. The high-performance LineJammer-SS is competition-proven and offers maximum diameter line-cutting ability for ASA and IBO outdoors competition. Features the BullDog™ Nock Collar for added strength and protection.
