The ultimate grip on the tip, HN has super frame strength and the added benefits of a tang for wrapping rock solid on heavy gear. Available in "wire line tough" SiN. Inspired by the extra strength provided by the "tang" on MN tops, HN heavy tops are best put to the test on heavy offshore trolling and boat rods. Deep pressed ring and Fuji's proprietary Silicon Nitride ring (used for ball bearings in jet engines!) are the keys to the reliable performance offered by HN Tops.
