Graphite frame, sideplate and rotor for reduced weight. Diecast aluminum spool for casting performance and durability. Varispeed™ - By using an oval oscillation gear, we are able to provide a consistent spool speed for an even line lay which results in excellent castability and manageability. Super Stopper® II is a one-way roller bearing that eliminates backplay for solid hooksets, yet can be turned on or off to allow back reeling. Ported Handle Shank reduces the overall weight of the reel. Dyna-Balance® - similar to balancing a tire, we use counterbalancing techniques in the rotor to eliminate wobble during the retrieve. Power Roller® II is an oversized line roller that reduces twist from casting and retrieving and is enhanced with a tapered area on the support to help line get onto the roller quicker.
