Scientific Anglers Mastery Double Taper DT Fly Line, floating

For years, SA Mastery Series lines have been among our most-popular and best-performing lines. While some things have changed, one thing hasn’t: Mastery Series lines still deliver just as well as—if not better than—they ever have before.

With our AST slickness additive, Dry-Tip technology, color change at the rear of the head, and SA•ID identification system, Mastery lines are still the best smooth lines at their price point on the market.

From dry-fly purists to tarpon-chasing poon hounds, the Mastery Series from SA provides every angler the lines they need to catch the fish they crave.

Double-taper fly lines may not be the most versatile of the bunch, but they’re very good at what they’re designed to do: delicate work at shorter distances. An excellent dry-fly line, the Mastery Double Taper excels at presenting flies with a touch of grace, which is extra handy on spring creeks and smaller streams.
