I've always used SPECTRA braided lines I get from West Marine. Never failed over years use. Spectra in general: Braided Spectra Fiber Line is not affected by saltwater, UV rays, or most chemicals and solvents. The life of PowerPro line is much longer than monofilament lines (as a rule of thumb, it lasts five times the life of monofilament line). 73, Larry N6NC
