SpiderWire Ultracast FluoroBraid is the first braided superline designed to sink like fluorocarbon line. FluoroBraid combines the sinking properties of fluorocarbon line with the classic strength and castability of SpiderWire braided fishing lines. This line features a breakthrough Gore fluoropolymer and Dyneema fiber blend, providing a more direct line from rod tip to lure. The result is less slack in your line for ultimate sensitivity and faster hook sets. SpiderWire Ultracast FluoroBraid is 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.
