6th Sense Curve 55 Crankbait - The 6th Sense Curve 55 utilizes a specialized weight system that will make this smaller sized crankbait dance in the water with an abstract side-to-side motion. Diving in the 5-9 foot depth range with a tight wobble, the Curve 55 can be cranked along rocky banks and gravel flats, over grass, and near just about any other structure.
