"Stillwater is my secret weapon for catching more and larger fish in very-clear still and flowing waters with swimming flies. Since I've discovered its effectiveness I've consistently had better success than with any other natural or slow-sinking fly lines."
- Dave Whitlock, The Art & Science of Fly Fishing

Mike at Blue Creek Fly Shop - "I have casted this line for years - it casts great especially with leeches and woollybuggers."

Mastery Titan, Scientific Anglers

Quick-Loading Floating Taper for Big Flies

You’ve got articulated streamers hanging from the lampshade on your desk. You think in terms of black, white, or olive. The term conehead doesn’t refer to an old comedy sketch. We totally get it. And that’s why we designed the Mastery Titan. If you have an all-encompassing need to throw big flies for big fish, then look no further. This fly line is made for you.

Loads quickly and delivers the biggest flies to the furthest targets
Excellent turnover due to short, powerful head and short front taper
Ideal line for boat or wade fishing
For temperate climates
Braided multifilament core

Mastery Double Taper Fly Line by Scientific Anglers

Floating Dry-Fly Line

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.

Double-taper lines are extra-delicate for subtle presentations
Excels in short-to-medium distances with dry flies and smaller nymphs
The ultimate fly line for chasing trout in close quarters
Braided multifilament core

Double check. If you’ve got a bucket list full of huge fish, we’ve got your line right here.

Loads quickly and delivers the biggest flies to the furthest targets
Excellent turnover due to short, powerful head and short front taper
Specially designed for tropical environments
Shooting Texture reduces friction, providing longer casts, easier pick-up, and increased durability
Built on a 100-lb. monofilament core for tropical climates

Sonar Titan Clear Tip, Scientific Anglers

Sinking Clear-Tip Fly Line

Who says you can't be stealthy when you're chucking foot-long streamers at pike or muskie? The SONAR Titan Clear Tip fly line provides all the advantages of our Titan taper--easy loading and effortless turnover to name a few--and tops it off with an intermediate sinking clear head. When your quarry has eyes the size of dinner plates (almost), every little bit of stealth helps.

Loads quickly and delivers the biggest flies to the furthest targets
15? clear tip for stealthy presentations
Excellent turnover due to short, powerful head and short front taper
Slow sink rate gets flies just below the surface
Mastery Texturing reduces friction, providing longer casts, easier pick-up, and increased durability
For temperate climates
