Scientific Anglers Mastery Trout GP Fly Line

The Trout GP Fly Line is a versatile general-purpose trout line designed for anglers who prefer a more finesse-focused presentation. Built with the tapered belly design from the Infinity series, Trout GP features slightly longer front and rear tapers with a ¼-size-heavy weight profile for smooth loading, controlled turnover, and accurate casts.

Compared to Infinity, Trout GP offers a lighter, more refined feel while still delivering dependable all-around trout performance. It is a great choice for anglers who do not regularly fish heavy streamers, bulky indicators, or oversized nymph rigs.

Finished with a braided multifilament core, Trout GP provides smooth handling, reliable performance, and the versatility needed for everyday trout fishing.
