The Berkley FireLine Fused Original can rightfully be called a super-line! This term was first used with the launch of FireLine in 1996, and today FireLine still is! It is not a standard braided or nylon line, but a Thermally Fused line, which means that the line is treated with Dyneema fibres. This makes the line smoother and more flexible than traditional braided line, optimized for further casting and suitable for all types of predatory fish!
