SONAR GRAND SLAM CLEAR TIP FLY LINE 8-Foot clear intermediate sink tip for ultra-wary fish. Short, powerful front taper for turning over heavy flies on long leaders, even in a saltwater wind. Belly is over-weighted nearly a full fly line to load your rod immediately for those quick, short presentations when visibility is sparse. A longer rear taper helps transfer the energy smoothly into the belly of the line. Color change to show optimum loading point. For demanding tropical conditions. WF6F/I thru WF12F/I.
