Fly Line Backing

The right backing depends on your reel capacity, target species, fly-line size, and the strength required for your fishing. Standard Dacron backing is dependable and easy to handle, while thinner high-strength backing can provide greater capacity on the same reel.

Consider breaking strength, diameter, spool length, visibility, and compatibility with your reel and fly line. Always check the reel manufacturer’s recommended backing capacity before loading the spool.
