Which fly reel backing is right for me? Gel Spun Braid VS Dacron

When selecting backing for a flyfishing reel, two common options are gel-spun braided backing and Dacron backing. Both have their advantages and drawbacks, depending on the type of fishing you're doing. Understanding the differences between these two materials can help you make an informed decision on which is best suited for your needs.

What is Fly Line Backing?

Fly line backing is an essential part of your flyfishing reel setup, especially when targeting large fish species that can take long runs. The backing is attached to the arbor of your reel and provides additional line capacity beyond your fly line, allowing you to handle long runs without running out of line. There are two primary types of backing: Dacron and gel-spun braided backing.

Dacron Backing

Dacron, a polyester-based material, has been a staple in flyfishing for decades. Known for its reliability and durability, Dacron is a solid choice for most flyfishers, especially those targeting freshwater species.

Advantages:

1. Affordability: Dacron is less expensive than gel-spun backing, making it an attractive option for flyfishers on a budget.
2. Ease of Handling: Dacron backing is softer and less prone to tangling compared to gel-spun options. Its flexibility makes it easier to handle, especially when spooling it onto the reel or dealing with a fish on the line.
3. Durability: While not as strong as gel-spun, Dacron is still highly durable and can withstand the demands of most freshwater fishing situations.

Disadvantages:

1. Lower Capacity: Dacron backing has a lower strength-to-diameter ratio, which means it takes up more space on the reel. This can be a limitation when you need extra backing capacity for large or fast-running fish.
2. Heavier: Dacron backing is heavier than gel-spun, which can be a factor for flyfishers trying to keep their setup as lightweight as possible.

Gel-Spun Braided Backing

Gel-spun polyethylene (GSP) backing is a relatively newer option in the world of flyfishing. It is favored by many saltwater flyfishers and those targeting larger, more powerful species due to its impressive strength and thin diameter.

Advantages:

1. Higher Strength-to-Diameter Ratio: Gel-spun backing is much thinner than Dacron for the same breaking strength, which means you can fit significantly more backing on your reel. This is especially beneficial when fishing for species like tarpon, bonefish, or permit, which can take long runs.
2. Lighter Weight: The thinner diameter of gel-spun backing also translates to a lighter overall setup, which can be a plus for those looking to minimize weight.
3. Abrasion Resistance: Gel-spun fibers are more resistant to abrasion, making them ideal for fishing in environments where your line might encounter sharp objects, like rocks or coral.

Disadvantages:

1. Cost: Gel-spun backing is more expensive than Dacron, which might be a deterrent for flyfishers on a tight budget.
2. Handling Challenges: Gel-spun backing can be more challenging to handle than Dacron. Its thin, slick nature makes it more prone to tangling, and it can be more difficult to work with when tying knots. Additionally, the thin diameter can cut into your fingers or fly line if not handled carefully during a fight.

Which Should You Choose?

The choice between Dacron and gel-spun braided backing ultimately comes down to the type of fishing you plan to do and your personal preferences.

• For freshwater fishing and budget-conscious flyfishers, Dacron is often the better choice. Its ease of handling, durability, and affordability make it a reliable option for most situations.

• For saltwater fishing or targeting large species, gel-spun backing is generally the preferred choice due to its high strength and thin diameter, allowing for more line capacity and better performance in demanding conditions.
