​For years, Scientific Angler's leader and tippet materials were marketed and advertised as being something they weren't. The diameters, breaking strengths, and performances just weren't accurate - or on par with their own rigorous standards. Scientific Angler needed to fix that.

Over the past several years The folks at SA have meticulously researched, tested and developed what they believe are the best leaders and tippets ever produced. Their new nylon and fluorocarbon materials are, simply put, the strongest and most reliable they have ever created, with the highest knot strength of anything tested. Period. These breaking strengths and diameters have been put to the test more times than a lab rat, and we are finally in-line with SA's exacting demands.

The bottom line is this: you can fish the other stuff, or you can FISH THE TRUTH
