Mastery Series MPX Taper Fly Line

Need a line that will drop a dry fly right in the feeding lane of a brown trout, huck wooly buggers around the river, and turn over heavy nymph rigs? Spool up the Scientific Anglers Mastery Series MPX Taper Fly Line. Designed with versatility as a priority, this well-rounded line puts plenty of mass at the front of the line to deliver more power with each cast, but still has plenty of finesse when you're slinging tiny midges to big, picky rainbows this winter.

Top Notch Mending Abilities

I've put it through the wringer

I have always been an advocate of RIO fly line, but I thought I would give this product a try. I absolutely love this line. It’s accurate and has great tapered weight. I was impressed with its mending abilities. This is a solid product, and I highly recommend it.
