Our most versatile and most popular rod model. The 590-4 R8 CORE handles trout flies of nearly any size, lines of varying densities and does so with superb feel, accuracy, and line control. With R8 CORE we enhance that two-way connection from hand to fly and back for greater feel, flow and control. This Amplified Two-Way Feedback Loop, due to our new axial fiber formulation, allows you to feel when the power needs to be applied throughout the cast, presentation, and when applying the appropriate pressure to fish – ultimately giving you the angler Complete Control.
