Smoother casting, ultra sensitive and super strong! Older first generations superlines were made of abrasives that would cut rod guides and take a toll on equipment. This problem has been solved by super slick, non-abrasive Spectra Fiber composition and unique EBT ( Enhanced Body Technology ) processing. It's rounder and more compact for an unbelievable strength-to-size ratio. The line ties more easily and holds knots better. It has near-zero stretch and no reel memory. When you cast, Spectra Fiber sails effortlessly through guides for longer distances and maintains its performance over a greater amount of time versus any regular monofilament.
