Scientific Anglers Mastery Wet Tip Express Sinking Tip Fly LineMastery Wet Tip™ Express is designed to deliver flies deep, and fast. They are similar to shooting head/shooting line systems, but all in one piece and with significant advantages. Each version has a tapered 25’ sinking head for improved casting performance and an increased diameter floating “handling line” behind the head for improved line control, casting, and durability.  The larger than normal diameter running line allows for increased durability and greatly reduced tangling and features Advanced Shooting Technology (AST) floating coating for reduced friction, and increased durability.

Wet Tips™ Express feature a standard braided multifilament nylon core and feature sink rate heads of 150 - 4ips, 200 - 4.5 ips, 250 - 5 ips, 300 - 5.5 ips, 350 - 6 ips, 450 - 7 ips, 550 - 8 ips (ips – inches per second).  Wet Tips™ Express utilize an AST coating in the floating belly section, which offers long lasting slickness for better shootability and better floatation. The durable AST coating is a key element in keeping the lines from picking up dirt and algae allowing your line to shoot farther and float higher for longer periods.

Scientific Anglers Ultra 4 Fly Fishing Fly Lines available at Traditional AnglerMastery lines incorporate Scientific Anglers' Advanced Shooting Technology. The unique 'dry-slick' coating enhances every aspect of floating line performance. In just three short years, amazing AST - Advanced Shooting Technology - has redefined fly-line performance. Using a patented coating process, AST is integrated within the line coating to achieve a unique 'dry' slickness that keeps the line permanently slick and continuously clean. Try an AST line just once, and nothing else will do.

The dry slickness of AST prevents dirt and algae from clinging to line, which means line stays cleaner and floats higher for longer intervals. AST isn't just permanently slick - it's lightning slick for the fastest, smoothest shooting of your life. With AST, line shoots through the guides virtually friction-free and keeps on doing it for the life of the line - without the need for dressing. Plus, because the line stays so clean and free of debris with AST, Scientific Anglers lines are significantly less prone to wear and corrosion.
