Scientific Anglers Mastery Trout GP is a line similar to the Infinity, but with slightly extended tapers and a slightly lower total weight. This makes the line an excellent choice for lighter general-purpose trout and grayling fishing when heavier flies or indicator rigs are not required. The line's long rear taper makes line control easy during the drift.

Scientific Anglers Mastery Trout GP features:

• Utilizing the tapered belly from Infinity, Trout GP has a slightly longer front and rear taper and ¼ size heavy weight scheme. Compared to Infinity, Trout GP leans more finesse but is still a capable general purpose trout line.
• The choice for anglers who don’t consistently fish heavy rigs like large streamers or bulky indicators.
• Braided multifilament core.
• *Grain weight for the first 30′.
