Chasing giant trophy bass can be tough on your fishing equipment, especially your swimbaits. Violent strikes from some of the biggest predators in the lake will eventually damage a swimbaitís soft plastic components, and the Spro BBZ-1 Replacement Fin & Tail Set provides a relatively inexpensive way of prolonging the life of your Spro BBZ-1 8î Swimbait. Available in Rainbow Trout and Siver Fish patterns, the Spro BBZ-1 Replacement Fin & Tail Set allows you to easily replace the soft plastic fins and tail of your 8î BBZ-1 Swimbait - keeping it in the water and catching fish.
