The PRO Saltwater All-Rounder Smooth Fly Line is a completely reimagined and advanced compound taper from its predecessor. This line is the do-it-all saltwater line that has the power to reach that distant target, and a fast-loading, front compound taper to make a few quick shots in a row. The dual belly helps add stability to the line, and allows for easy casting and pickups. It is built on our multifilament core so it can easily perform in cool weather. Can also be very effective for larger freshwater application such as bass, pike or carp.
