Fly fishing requires a high-quality fly line, especially in deep, turbulent waters. With so many brands and flylines available, choosing the right one can be overwhelming. In this article, we will explore some of the top fly-line brands that have gained a strong reputation among fly fishing enthusiasts.

We will delve into the unique features and innovations that make these brands stand out, including Scientific Anglers' Mastery series with its AST technology that reduces line memory and improves casting distance, RIO's Gold series with its versatile taper design that suits both beginners and experienced anglers, Orvis' Hydros HD series with its textured surface that minimizes friction and enhances floatation, and Airflo's Super-Dri Elite series with its hydrophobic coating that repels water and increases buoyancy. 

Best Lines for Colorado


  • Floating Weight Forward (FWF) 5wt Line: This is considered a go-to fly line for most fly fishing situations in Colorado. The weight-forward design helps with long-distance casts and provides excellent control for precision casting. The 5wt designation is popular as it offers enough power to handle larger fish yet remains delicate enough to present smaller dry flies. It is versatile and suitable for fishing in rivers, lakes, and streams, making it a reliable option for various fly fishing scenarios.
  • Sink-Tip Line: Colorado features numerous rivers and lakes with deep sections that fish like to inhabit. A sink-tip line can be highly effective when targeting fish in deeper waters. This type of line features a sinking tip section, usually 5 to 15 feet long, allowing anglers to present streamers or nymphs at the desired depth. It is particularly useful for imitating baitfish or insects closer to the bottom. By combining a sinking portion with a floating running line, anglers can cast further while controlling the presentation.
  • Double Taper (DT) Line: While weight forward lines are popular, some anglers prefer the versatility and delicacy of double taper lines, especially in smaller streams or calm waters. A double taper line has a uniform thickness along its length, which can provide a more delicate and accurate presentation. With its ability to make softer presentations and roll casts, a DT line can be highly effective when precision is crucial, such as fishing for wary trout in clear waters or targeting rising fish.

Note that anglers' preferences for fly lines may vary, and different fishing conditions, target species, and personal fishing styles can influence the choice of fly lines. Gathering insights from local fly shops or experienced anglers in Colorado can provide valuable recommendations tailored to the specific fishing locations and conditions you plan to explore.
