Stillwater Slow Sink Intermediate

Two Size Heavy

Take control of subsurface presentations with the Scientific Anglers Stillwater Slow Sink Fly Line, a premium sinking fly line designed specifically for stillwater anglers targeting trout with nymphs, streamers, and multi-fly rigs. Featuring Scientific Anglers’ AST Plus technology, the Stillwater Slow Sink delivers exceptional slickness, increased durability, smooth shooting performance, and dependable handling.

The Stillwater taper is built two line sizes heavy, helping load rods efficiently while providing the power needed to cast multiple flies, long leaders, and longer distances. Textured hang markers positioned 10 and 20 feet from the tip provide an easy reference when controlling depth and retrieving flies close to the boat or bank.

Available in different slow-sinking configurations, the Stillwater Slow Sink allows anglers to effectively cover water just beneath the surface or at greater depths while maintaining excellent control throughout the retrieve.
