Scientific Anglers Amplitude Smooth Trout Standard Fly Line

You’re on the famous Letort Spring Run, there’s a hatch of sulphurs beginning to come off, you see the first snout pop up, then a second, but the water is vodka-clear, full of slow-rolling micro currents, and you’re standing 60’ away, let SA guide you to success with their Amplitude Smooth Trout Standard Fly Line. Designed to excel in technical dry fly situations, Scientific Anglers equips this series of lines with an elongated front taper, true-to-weight line rating, and their AST Plus technology that combine to help you land your fly delicately and make long casts without impacting accuracy. SA’s Amplitude Smooth design further increases this line’s performance by decreasing drag by up to five times and boasting durability that’s eight times that of traditional fly lines. Available in line weights 2 through 6, SA has an option whether you’re throwing large hex patterns at whopper browns or sending the perfect drift downstream to wild brookies on an ultra-clear meadow stream.

Features

SA Line ID, AST Plus, and Improved Dry Tip - SA makes early morning trico spinner falls that much easier 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 to the lot with a 5-weight line and a - weight rod. 

When the sun is shining and the trout are rising but you need to make a long precise cast, SA’s AST Plus tech is there to help. AST Plus ensures excellent durability and shootability for the line’s lifetime. 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.

From helping your mends to making a subtle pickup and recast of the line and all the way to setting the hook deliberately, SA’s Improved Dry Tip Technology helps you defeat all of the technical difficulties of the dry fly game. 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, Wet Flies, and Nymphs - Designed to handle the more technical aspects of fly fishing for trout, the Amplitude Smooth Trout Standard Line’s elongated taper is an excellent choice when presenting dry flies, but you can also count on it if you’re drifting a nymph or working a wet fly downstream. 

Temp

Cold/Moderate - February midge hatches to summer flying ant swarms, Scientific Anglers sets their Amplitude Smooth Trout Standard Line up for use in cold to moderate waters. This allows you to fish in just about any water temp that’s suitable for trout from winter through summer.  

Taper/Weight

Elongated Front Taper - Made for technical dry fly presentations, tough fish, and clear water, Scientific Anglers utilizes an elongated front taper and a true-to-weight line weight on their Amplitude Smooth Trout Line. This configuration allows you to subtly land your fly and provides pinpoint accuracy, so you never find yourself in a situation that’s too tough to manage.
