The ferrule is the connection between sections of a fly rod. Ferrules are installed so a rod can be disassembled and conveniently carried and stored. Action is influenced by the rod's material, taper design, length and such fittings as ferrules and guides. A medium-action rod is limber when flexed and unflexes smoothly when loaded. A medium-action, progressively loading fly rod is the best rod with which to learn the sport.
Medium action is the most adaptable to a person's individual timing and reflexes.
This combination is light, it provides enough power to cast 20 to 60 feet, and it can control most of the flies used to fish for trout, bass and panfish. After you begin to master the basic fly-casting strokes, qualified instructors will be able to advise you on which action best suits your own reflexes and coordination level.
