FC The Rock is a medium hardness supple fluorocarbon line ideal for the angler looking for a strong, low-visibility line for a variety of angling targets. The line itself is naturally clear and has a low water absorption and memory. It features a consistent diameter all the way which offers anglers less twist and hence weak points along the length of the line, making it excellent as an all-the-way-through option as well as its intended purpose as a leader material. Available in 100m spools of 8, 10, 12, 16 and 20lb, it is ideal in any situation where strong but stealthy presentations are required.
