Scientific Anglers Amplitude Smooth Infinity Warm Fly Line

With Scientific Anglers' Amplitude Smooth Infinity Warm Fly Line, versatility is the name of the game. SA's Amplitude Smooth series of fly lines are some of the best on the market—designed around long-lasting durability and performance, this series offers five times less drag and eight times the durability of other lines, giving you everything you need to fish hard for years to come. With a tropical coating and coldwater core, this line is built for medium to warm water pursuits, making it a great choice whether you're drifting adult dragonfly imitations over rising trout or working the jungle for some brutish peacock bass. Made in line weights 5 through 9, the Amplitude Smooth Infinity Warm Fly Line provides excellent versatility over a wide range of species and rod weights.

Features

SA Line ID, AST Plus, and Improved Dry Tip - When it comes to fishing, it's important to remove every bit of error you can, and Scientific Anglers' Line ID makes it easy to always grab the right line or spool. A quick identifier, SA Line ID is an integrated marking system in the first 1'-2' of the tip section that ensures you won't accidentally drive into the parking lot with a 6-weight line and an 8-weight rod. Whether you're shooting line upstream to a rising fish or stripping a streamer back up a long run, Scientific Anglers' AST Plus ensures excellent durability and shootability. 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 float higher, last longer, and shoot further. To keep your tip floating and prevent unnecessary missed strikes, Scientific Anglers includes their Improved Dry Tip. The Improved Dry Tip is a unique series of microballoons that makes your tip float twice as high as a standard fly line—this undoubtedly gives you an upper hand when you need to make quick hooksets.

Uses

Dry Flies, Nymphs, and Streamers - It's not often that you get a line that can softly drop a dry fly just as well as it can bomb a size 3/0 articulated streamer, but the Amplitude Smooth Infinity Warm Fly Line pulls it off with ease. Built a half-size heavy with a versatile taper, this is a line that can present nearly any fly in your box. Whether you're drifting nymphs under an indicator, swinging streamers down and across, or working a dry fly as you walk upstream, this line does it all.

Temp

Warm/Moderate - Scientific Anglers makes their Amplitude Smooth Infinity Warm Fly Line family of lines for warm to moderate temperatures. This allows you to fish for things like summer bass and trout all the way to hotter-climate species like dorado and peacock bass. However, if you try and fish this line in a cold setting, you'll find that it quickly stiffens up.

Taper/Weight

More Mass Towards the Front of the Head - The Amplitude Smooth Infinity Warm Fly Line was built around versatility, and true versatility starts with a well-thought-out taper. This line is built a half-line weight heavy and features a long head with a considerable front taper, giving it all of the power and loading capability that you need, while also mending like a champ and offering both accuracy and a delicate presentation when you need it.
