Designed to tame what's arguably the toughest inshore fish on the planet, the Scientific Anglers Amplitude Smooth Titan GT Fly Line has you covered when you've finally got a pair of GTs swimming in front of you and your time to make the perfect delivery is now. The Amplitude Smooth Titan GT Line is built one line size heavy to load fast-action rods and facilitate quick shots at fleeing fish, and with SA's AST Plus technology, it's never been easier to squeeze a crucial extra few feet out of your cast. Built to withstand tough environments and fish that pull like no other, this floating line utilizes Scientific Anglers' 65-lb Core tech and comes with 100lb braided add-on loops for nearly invincible strength. When you're on the half-hour mark of the fight, you'll know things are coming to a close when you see the high-contrast sighter integrated into the back of the line—the battle might not be over, but this mark lets you know when you're darn close. Made in line weights 11 and 12, this line has everything that you need to chase these tough fish, and whether you're popping a massive NYAP at the edge of an atoll or stripping a big brush fly over an underwater reef, you can count on the Amplitude Smooth Titan GT Fly Line to get the job done.
Features
SA Line ID, AST Plus, Tropi-Core, Sonar Sinking Technology, 65-lb Core - Whether you're quickly identifying which spare spool to grab or packing a backup line in preparation for the worst, SA's Line ID makes identifying which line you have in hand as easy as it gets. Line ID is an identification system at the tip 1'-2' of the line that quickly tells you what line you've got in your hand.
Not only do GTs pull like few fish can, but they're super fast and race across reefs and on flats. When you need to match your cast to that fish's speed and dial in your presentation from nearly a full fly line's length away, SA's AST Plus tech is here to help. AST Plus is SA's new formulation of their patented dry-slick technology that's 50% slicker than their previous formula and up to 200% more durable than other lines on the market. A solid addition, AST Plus makes your line last longer, float higher, and shoot further.
Fishing in some of the hottest habitats on the planet for some of the toughest fish out there requires special attention to your line's temperature rating and how hard you can pull back on these fish during the fight. Tropic-Core adds durability while preventing your line from going limp or failing in hot water or an even hotter boat deck, and SA's 65-lb Core sports an extremely tough tensile strength of 65lbs, allowing you to put the heat to a fish at those crucial points of the fight.
Uses
Streamers and Poppers - GTs are known to crush flies, and whether you need to present a fly under the surface or make a ton of commotion to draw a fish in, this floating line has the taper you need to deliver even the largest streamers and poppers.
Temp
Tropical - Pursuing GTs is pretty much exclusively a warm-to-tropical water situation, appropriately so, Scientific Anglers configures this series of lines for use in warm and tropical waters. This allows you to fish from hot boat decks or wade in tropical water without fail or your line getting soft.
Taper/Weight
More Mass Towards the Front of the Head - Designed to throw bulky and air-resistant flies while using ultra-stout fast-action rods, Scientific Anglers makes the Amplitude Smooth Titan GT Fly Line with an aggressive taper that's overlined by one full line weight. This 32.5' head and compact taper allows you to cast any fly in your box, regardless of how much the wind picks up.
