From casting Catskill style dry flies on a clear spring creek to lining up a true classic of a bamboo rod, Scientific Anglers' Amplitude Smooth Double Taper Fly Line is a true-to-weight line that's ready for it all. Pairing a traditional double taper with their AST Plus slickness technology, this line does a fantastic job at delivering long casts with dry flies and small nymphs, while SA's Improved Dry Tip tech ensures that your tip is floating nice and high to prevent drag and allow you to subtly pick up your line and recast over that rising snout. Made in line weights 3 through 5 in a natural yet easily seen on the water combo of green/leather/buckskin colors, the Amplitude Smooth Double Taper Line lets you fish anything from remote freestone streams to the slow, clear waters of a limestone brook.
Features
SA Line ID, AST Plus, and Improved Dry Tip - SA makes early morning sessions easier than ever with their SA Line ID. 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 mountains with a 5-weight line and a 3-weight rod.
On those bluebird days when the sun is high, the fish are looking up, and you need to put a line's distance between you and that rising trout, SA helps you extend the length of your cast with their AST Plus Technology. 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 and spooked fish, Scientific Anglers includes their Improved Dry Tip tech in this line. The Improved Dry Tip is a unique series of microballoons that makes your tip float twice as high as a standard fly line.
Uses
Dry Flies, Nymphs, and Streamers - The double taper configuration on Scientific Anglers' Amplitude Smooth Double Taper Fly Line provides excellent versatility on the water. While this line is a great choice for dry flies and nymph patterns, it'll still let you subtly land a streamer whenever you come across a window of opportunity to feed a predatory trout some meat.
Temp
Cold/Moderate - Built to handle all of the environments that trout call home, Scientific Anglers equips the Amplitude Smooth Double Taper Line for use in cold to moderate water. This allows you to fish in the dead of winter just as well as you'll be able to cast beetles in a meadow during the middle of summer.
Taper/Weight
Double Taper - As you might guess by its name, the Amplitude Smooth Double Taper Fly Line sports a classic double taper. This taper is a dream to fish on bamboo and glass rods, and its true-to-weight build allows you to delicately land your fly while making those long casts to weary fish. A great choice across a range of environments and fly types, the taper on this line is tough to beat when you're after a more traditional feel and line.
