Taper Diagram


  • Cold water temps- When fishing cold water streams and rivers, these lines are the optimal choice. They remain supple, refuse to coil, and outperform lines built for warmer climates.
  • Medium water temps- Lines featuring this icon are excellent all-around lines for almost any climate. While they may turn limp in tropical conditions, these lines will perform well in moderate and cool climates.
  • Dries- Dry flies float on the surface of the water, imitating a hatching insect or one landing to lay eggs. Lines with this designation are designed to handle dry flies with a delicate touch.
  • Nymphs- Nymphs are tied to imitate aquatic insects that live underwater. This icon signifies a line designed to fish weighted nymphs for a variety of species.
