Fly fishing leaders for bluefish, barracuda, and pike. This is the best bite-guard system for the sharp teeth of saltwater fish we've ever seen! Not only are these leaders easy to use-they're reusable. The twist is prefabricated in a way that is easy to twist and untwist many times over. Easy-to-follow directions are included. Each package of fly fishing leaders contains six guards in a rigid plastic tube to keep them straight.
