Sienna is a well-balanced, high performance built reel at an amazingly affordable price. Incorporating the Propulsion Line Management System for longer casts and reduced wind knots, the Sienna uses Super Stopper II for instant anti-reverse with no back play. Available in a sizes suited for everything from freshwater to inshore fishing. G-Free Body technology has been developed to shift the reel’s center of gravity closer to the rod. By moving the center of gravity closer to the anglers hand, the G-Free Body helps to reduce fatigue and enhance casting comfort. The most obvious component of the Propulsion Line Management System is the new Propulsion Spool Lip design. Through tens of thousands of casting tests and computer simulations, Shimanos new spool lip design provides longer casting distances than a standard spool lip design while also preventing backlashes and wind knots from forming.
