Rannari - Coated Ultra Thin Running Line. Rannari - Coated ultra thin running line was designed to meet a significant demand from coastal anglers who use shooting heads. In addition there are growing demand for thinner running lines that runs smoothly through rod guides and are easy to handle. Especially in Danish coastline many people have been using our Ultra Light Nymph euronymphing line as a running line. We've been asked to delevop this line further with bigger front loop, so here it is now. We've made this Rannari from 12lb braided core to achieve the thinnest possible diameter. Phthalate free.
