Frequently Asked Questions (FAQs)

1. What fly line backing to use?

The most typically used backing is braided nylon in either 20lb or 30lb test strength. For light duty saltwater and most freshwater fly fishing, 20 lb is fine. The heavier gauge 30 lb is generally reserved for tarpon and other larger saltwater fish.

2. What material is fly line made of?

Most fly lines are manufactured with a core of braided nylon or dacron. This core is then coated with PVC, which has been treated with various substances such as microscopic glass spheres for floatability or other additives that cause the line to sink at various desired rates (called multiple density production).

3. Do you need to stretch your fly line?

Once the line is on the water, it won't lie straight, so there's unnecessary slack between you and your fly, which can make setting the hook more difficult. It's also important to have a straightened line when you're casting out of a boat because coiled line will tangle more.

4. Can you use braid for flyfishing?

Using Braided Fishing Line As Fly Backing The answer is yes! Fly shops around the country use braided fishing line to back their fly reels.
