The DUO Ryuki is a heavy-weight sinking minnow designed with a flat, low-centre-of-gravity body to produce a sharp, responsive action. This lure delivers a swift initial action response, quickly reacting to rod manipulations and enabling a series of rapid twitches over short distances. Its high swimming performance allows it to tackle powerful and complex currents in main river flows with ease. Additionally, it maintains a stable casting posture, offering exceptional casting distance and accuracy, allowing anglers to precisely target their sweet spots. The Ryuki 45S excels in shallow headwaters with limited water volume and small urban streams. Despite its compact size, its high-density design ensures outstanding casting performance, making it equally effective for main river fishing scenarios.
