With its weight-forward design, the Mastery Short Belly Taper Fly Line from Scientific Anglers is well-suited for single-handed spey casts. Short head and bright-colored belly provides effortless handling and line control at short to medium ranges. It turns over weighted nymphs and streamers yet offers light presentations when used with long leaders. Advanced Shooting Technology (AST) delivers continual line slickness, so you can cast farther with ease. Plus, it allows the line to shed dirt, algae and other drag particles. Scientific Anglers Line Identification (SAID) allows you to identify your lines at a glance. Braided multifilament core with welded loops. Made in USA.
