We've all been there. Standing in our local fly shop when the associate asks "What style of fly reel do you prefer?" For many freshwater fishing situations, the reel is mainly a line holder, but for hard fighting or big fish the reel becomes one of the most important pieces of equipment.
The arbor is the center of the reel that the backing and line are tied to and wound around. There are three general sizes of arbor: large, mid and small. The arbor you pick is not just about the look of the reel. Arbor size affects the weight, capacity and speed of retrieve of the reel.
