In the "Spey World" some anglers like conventional coated shooting line because it is easy to hang on to. Others like monofilament because it is slick and shoots through the rod guides with reduced friction for longer casts. Now you can have your cake and eat it too, or more to the point you can have a shooting line that is both monofilament and is coated for easier grip. It is called GripShooter, which is a super hard, slick finish oval-shaped nylon shooting line with a bright orange handling line coated onto it for a better grip while casting. The main line is SlickShooter which has an extremely low coefficient of friction for long distance casts. These lines are "looped" for easy changing of shooting heads.
RIO 44-pound test GripShooter shows on this reel as red mono and orange handling ine. The blue line is a RIO Skagit Max, and the black line is T-14. GripShooter is one of the most popular Spey shooting line available.
