The MPX taper by SA is a guide favorite here at The Reel Life. This line delivers excellent action for those fast action rods. The taper allows you to turn over indicator rigs yet also delivers dry flies where you want them.
Built a half-size heavy, the MPX taper fly line picks up where the GPX left off. Redesigned with more mass toward the front of the head, the MasteryMPX from Scientific Anglers is a freshwater fly line that provides the same benefits as the good ol' GPX, but with an added emphasis on presentation.
