Drag
Reels should have an adjustable drag-system that maintains tension on the line. This is critical when attempting to land larger fish because it allows the fisherman to keep constant pressure on the line as the fish tries to escape.
Spool
The fly line is attached to the spool with backing. Many rods have replaceable spools, allowing a fisherman to use different types of line with the same reel.
Large Arbors
The arbor is the center section of the spool to which line is attached. Large arbors are growing in popularity because they allow for quicker line retrieval, better drag-tension control and reduced line coiling.
Single-Action
Most fly reels are single-action, which means one turn of the reel handle turns the spool a single time.
Line Weight
Reels are designed to cast a specific weight of line that must also match the specifications of the rod being used.
