Why We Like Scientific Anglers Mastery Series MPX Taper Fly Line

The new standard for Scientific Angler fly lines, the Mastery Series MPX Taper Fly Line is the improved version of the classic GPX Taper. Redesigned with more mass toward the front of the head, the MPX mixes power with an added emphasis on presentation, so we can 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. Designed with versatility as a priority, this well-rounded line is excellent with dry flies, nymphs, and streamers, so we can stay flexible on the water and catch more fish.

Great Fly Line

This fly line was recommended to me by a gentleman who works for LL Bean in their fly shop. This is an excellent fly line and casts very well. I use this fly line for mostly for bass fishing but it would be a great for trout.

Great fly line

I had purchased this line after reading an online review and used it on my 6 weight rod. It casts great and is very smooth. I just got a new 5 weight rod and immediately bought this line for the 5 weight
