Whether fishing for trout, bass, pike, or musky there are times when a large fly is the best option, and RIO’s Predator line series is designed specifically to cast them easily. Featuring a short, powerful front taper and plenty of weight at the front, the lines have no problem casting the biggest of flies with ease. Whether floating or sink tip, each line is built on RIO’s low stretch ConnectCore Plus for maximum performance, and features SlickCast—the slickest, most durable coating on the market.

There are 4 different density lines to cover every fishing situation:
A Full Floating line (F), for top water action
A Floating Line with 10ft of "Hover" Sinking line, then 10ft of Intermediate Sinking line at the front (F/H/I), for fishing in the top 2-3 ft
A Floating Line with 10ft of Intermediate Sinking line, then 10ft of Medium-Sinking line at the front (F/I/S3), for fishing mid-water
A Floating Line with 10ft of Fast-Sinking line, then 10ft of Extra-Fast Sinking line at the front (F/S5/S7), for getting down deep and fast

Designed To Cast Large, And Heavy Flies With Low-Stretch, Ultra-Slick Performance
 

• Short, powerful front taper to cast large and heavy flies
• Low-stretch ConnectCore Plus for the best in performance and smoothness
• Built with RIO's exceptionally slick, durable SlickCast
• Features RIO's SureFire tricolored measuring system for increased accuracy and distance control

ConnectCore - These lines open up new worlds of perception and sensitivity with ultra-low stretch performance. Soft, subtle takes become positive grabs, and without stretch to dull reaction times, hook sets are instant and sure. The secret weapon for success.

SlickCast creates the slickest, most durable coating on the market — producing the least amount of friction ever measured on a fly line. What does slick get you? For starters, line flies through the guides with higher line speeds for unprecedented and easy distance. The slick coating also allows anglers to fish more effectively as line slides out of the guides with less friction for extended drag-free drifts.

Multi Density Control - Multi Density Control is a combination of different density coatings along the length of a fly line. These different density coatings give anglers complete depth control when swinging a fly on a river, and perfect contact right to the fly. The exceptionally smooth, continuous blend in density changes results in extremely smooth loops while casting.

Features:
SUREFIRE is Rio's triple color marking system that improves casting accuracy by making it easy to gauge exact distances with a quick glance.

EASY ID RIO’s printed line marking system to allow anglers to quickly and easily identify each line.
