FluoroBraid sinks like a fluorocarbon line. It combines the sinking properties of a fluorocarbon with the strength and catability of SpiderWire braided fishing lines.
The braid provides a more direct line from rod tip to lure resulting in less slack and ultimate sensitivy for ultimate hook sets. It is great for casting crankbaits, trolling for extra lure depth, pitching softbaits in heavy cover, and on windy conditions to get your line down fast.
I recently bought some braid in 50lbs and plan on testing it on the La Zona dorado in a few weeks.
