    The unicorn of saltwater lines.

    Imagine a fly line that slices through wind, turns big saltwater patterns over with ease, but is still delicate enough to not spook tailing bones in crystal-clear waters and you have the Scientific Anglers Mastery Series Grand Slam Fly Line. Sound too good to be true? Well, you'd better believe it, because this mule of a line gets the job done whether you're casting tarpon toads on a windy day or stripping a little imitation crab meat in the flats thanks to a stout shooting head. Its Tropi-Core technology is acclimatized to deal with harsh saltwater environments, and the Shooting Technology Plus offers a silky smooth surface that screams through the guides and is easy on the fingers when you're spending a good portion of your day stripping line from the bow of a boat.
