Scientific Anglers Mastery Spey XLT Floating Fly LineThe Mastery Spey XLT line  has an extra-long taper and complex head allowing the caster to achieve the the longest championship-caliber casts in spey fishing.

The Mastery Spey XLT lines feature a braided multifilament nylon core with optimum air entrapment for minimum memory and maximum floatation.  It is coated with a specially formulated PVC with built in AST technology offering superior lubrication.

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.
