Airflo Superflo Power Taper - With an aggressive rear taper, and forward-biased concentration of mass, the Superflo Power Taper is designed to be anything but subtle. Even its coloration packs a punch. Developed specifically for modern, fast action rods, the Power Taper is perfect for anglers looking to cast big flies a country mile, and straight into a stiff, 20 knot wind at that. And our exclusive Polyurethane technology not only makes for a far more earth friendly fly line, it also provides the Power Taper with the strongest welded loops in the fly line business. Available in line weights WF3 WF9.
