Scientific Anglers Absolute Supreme Saltwater Tippet 30 M 10 lb

From AvidMax.com

A unique two-layer construction means this 100% fluorocarbon tippet is the strongest we've ever offered: up to 33% higher knot strength. A softer fluorocarbon outside layer helps knots seat properly and increases overall knot strength, while the harder fluorocarbon core provides exceptional tensile strength. Supreme Fluorocarbon tippet is also more supple than most other options, providing better drag free drifts while maintaining a stealthy footprint.Supreme Fluorocarbon is available on our patented cutter spool with our improved tippet band for easy identification and dispensing.
