When the giants of the deep are holding tight to the bottom in swift currents or plunging into the abyss of a deep lake, standard sinking lines simply won't cut it. You need a line that dives rapidly, cuts through the water column, and keeps your fly in the strike zone longer. The Specialty Series Compact Sink Type 9 is engineered for these exact scenarios. It stands as the world's most versatile sinking line, designed to perform flawlessly across all temperature conditions, giving you the upper hand whether you are chasing stripers in a rip or dredging for lake trout in the heat of summer. This line is built for the serious angler who understands that depth control is the most critical factor in presentation. It eliminates the frustration of waiting for a line to settle, allowing you to get down to the fish immediately and stay there throughout the retrieve.
Rapid Descent, Precision Handling
The engine of this line is its aggressive 28-foot Type 9 sinking head. With a sink rate of 8 to 9 inches per second (IPS), this head is designed to plummet. It drags large, buoyant flies down quickly, bypassing the unproductive upper water columns to reach the predators lurking below. Whether you are battling strong tidal currents or trying to reach a ledge in 30 feet of water, this head ensures your presentation gets where it needs to be.
Unique to this design is a 12-foot step integrated into the taper. This feature is a game-changer for handling and casting. It smoothes out the transition between the heavy head and the running line, aiding significantly in double hauling. You get a smoother, more powerful cast with less "hinging," allowing you to punch heavy flies into the wind with authority. Paired with an intermediate running line, you maintain a direct, straight-line connection to your fly without the slack caused by floating running lines.
Versatility and Durability Redefined
The Compact Sink Type 9 is engineered for durability, featuring a monofilament core built for powerful species like musky, pike, and striped bass. Its adaptable design remains slick and supple in both cool spring waters (50°F–70°F) and tropical heat. Equipped with our Shooting Technology (ST) coating and Heat-Tempered Surface Treatment, the line boasts an ultra-smooth finish that reduces friction and resists dirt for effortless casting. Dual Welded Loops ensure fast, reliable rigging for trophy fish. The 12-foot step design enhances handling and double-haul precision, while the Type 9 head sinks at 8–9 inches per second—perfect for deep-water targets. An intermediate running line provides a direct connection for superior strike detection. This 100-foot, weight-forward sinking line is a versatile choice for freshwater and saltwater, ideal for everything from bass and trout to salmon, steelhead, and false albacore.
