Fly Lines and Backing

Fly Lines

Fly lines are a crucial part of fly fishing gear, and choosing the right fly line for a specific fishing technique often determines success or failure. It’s important to understand that fly fishing is a very specific method of angling, and the fly line is what allows anglers to cast lightweight flies to the desired fishing spot. In our selection, you’ll find all types of fly lines from renowned global manufacturers.

Fly Line Designation

According to the American Fishing Tackle Manufacturers Association (AFTMA), fly lines are labeled with a profile type (e.g., DT, WF), a weight class number (e.g., 5, 6, 7), and a water behavior type (e.g., F, S).

Fly Line Profiles:

• DT – Double Taper

  As the name suggests, the line tapers evenly from both ends with the weight concentrated in the middle. This type is ideal for shorter casts and delicate presentations of artificial flies. Both ends of the fly line can be used.

• WF – Weight Forward

  The weight is concentrated toward the front of the line, giving it a club-like shape that focuses kinetic energy to carry the rest of the line forward. The front part of the line is used for casting, while the rear section remains toward the reel.

Fly Line Sink Rates:

• F – Floating: Fly lines that float on the surface.
• S – Sinking: Lines that sink beneath the surface.
• I – Intermediate: Lines with neutral buoyancy, slowly sinking.
• F/S – Floating/Sinking: Floating lines with a sinking tip.
