TECHNOLOGY: Built on a monofilament core that creates a stiff, slick line for quick feeding and less line sag between the rod guides, and an ultra-thin diameter to maximize sensitivity, and for lightning-fast hook sets. Core extends past the front end of the line to become a leader-resulting in no knots to get caught in the guides.
