FAQ

Our Streamer Sink Tip 10 T3 fly line is built for cold water environments and will perform best in temperatures between 30 and 70 degrees (F).

The taper design for our Streamer Sink Tip 10 T3 fly line was built featuring an aggressive head design integrated with a 10' type 6 sink tip. We designed this line with ultimate versatility in mind. Keep your fly down in riffles and heavy current, fish your streamer low & slow during the winter, or instantly get your fly down when casting off a boat.

The brown and light gray color combination distinguishes the transition between sinking and floating portions of the line, and provides depth reference on your retrieve. These colors are stealthy yet traceable in freshwater environments.

Cleaning your fly line is very important especially when fishing saltwater. Simply pull line off your reel into a clean bucket or tub of freshwater. Put roughly 1oz or more of Cortland’s Line Cleaner solution onto a clean rag or towel. Firmly squeeze the towel with Pro Line Cleaner around the line and slowly pull line through the towel. You should be able to see dirt or discolored streaks on the towel when finished.

Dominate the Shallows with the Streamer Sink Tip 10 T3

September 15th, 2025

When the target is aggressive trout holding in shallow creeks and rivers, you need a line built for precise, powerful presentations. The Streamer Sink Tip 10 T3 is engineered specifically for this demanding environment, allowing you to effectively fish large, enticing streamer patterns right where the fish are feeding. The core of this line’s performance lies in its aggressive, short taper design. This over-weighted head loads your rod quickly and with minimal backcasting, generating immense power to turn over heavy, air-resistant flies. Forget the struggle of casting articulated patterns or bulky sculpin heads; this line makes it feel effortless, helping you cover more water efficiently and accurately. The design ensures that whether you're roll-casting under overhanging branches or punching a long cast across a wide riffle, you have the control needed to place your fly perfectly every time. This line transforms challenging casting situations into opportunities, giving you the confidence to fish bigger flies and hunt bigger fish.

The business end of this line is a 10-foot, Type 3 integrated sink tip, which gets your fly down into the strike zone at a consistent rate of 3-4 inches per second. This sink rate is ideal for shallow rivers, creeks, and lake edges, allowing you to swing your streamer through promising runs without constantly snagging the bottom. Behind the sink tip is a high-floating running line, which provides superior line management, mending capabilities, and strike detection. The combination of a sinking tip and floating running line offers the best of both worlds: a direct connection to your fly and easy handling on the water's surface. Built on a durable braided nylon multifilament core, this 100-foot weight-forward line is a versatile tool for any angler targeting trout, steelhead, salmon, or bass with subsurface patterns. The dual-welded loops on both ends make rigging fast, simple, and incredibly reliable, letting you change leaders or attach backing without fumbling with knots, so you can spend more time fishing.

Engineered to excel in a variety of conditions, the Streamer Sink Tip 10 T3 is packed with advanced features to enhance its performance and longevity. Our proprietary Shooting Technology (ST) coating provides a glass-smooth, reduced-friction finish. This slick surface not only helps the line shoot through the guides for added distance but also resists dirt and grime, ensuring it remains slick over its entire lifespan. The line is also designed for four-season performance. Its Cold Temperature technology keeps it supple and memory-free in chilly conditions (30-50°F), while its Warm Temperature capabilities ensure it doesn't become soft or limp in milder weather (50-70°F). This product is a testament to over a century of American innovation. At Cortland Line Company, we have been refining fly lines for over 100 years, with every line proudly made in the USA. This dedication to quality and precision has allowed us to develop advanced fibers for critical applications in the medical and aerospace industries. When you choose Cortland, you're trusting a legacy of experience and a commitment to quality that will help you succeed on every trip to the water.
