The braid that sinks like a fluorocarbon. Spiderwire Ultracast FluoroBraid combines the sinking properties of a fluorocarbon with the strength and castablity of SpiderWire braided fishing lines. A breakthrough Gore fluoropolymer and Dyneema fiber blend provides a more direct line from rod tip to lure. The result is less slack in your line for ultimate sensitivity and faster hook sets. Great for power casting with crankbaits, trolling for extra lure depth, pitching softbaits in heavy cover and windy days when you need to get your line down faster.
