To truly get the most out of Shimanos Butterfly Jigs you need to fish them with a rod specifically designed for that type of fishing the Trevala. The Butterfly technique is based on an extremely productive Japanese-style jigging system. These are powerful, lightweight and light-action rods designed to be teamed up with high-speed, high-power reels. The Trevala rod blanks use Shimanos TC 4 Construction with new concept Fuji Alconite or Hardloy guides and a Fuji reel seat. The custom-shaped EVA fore grip and rear grip are more ergonomic, so you can spend longer days on the water. Hook keeper. Limited lifetime warranty.
