Scientific Anglers Amplitude Smooth MPX

The MPX is the line for anglers who fish bigger bugs more often than not — hopper-dropper rigs on the Weber in August, chubby Chernobyls during the Green River cicada madness, streamers on cloudy days. With more mass pushed toward the front of the head than the Infinity, it turns over wind-resistant flies with authority while keeping enough finesse for a clean presentation.

Built a half-size heavy on SA's Amplitude Smooth platform with the AST Plus slickness additive: five times less drag, eight times the durability, and a casting feel that makes your rod work the way it was designed to.

Why we like it

• Front-loaded taper — turns over hoppers, chubbies & streamers with ease
• Our pick for the Green River cicada window and summer terrestrial season
• AST Plus slickness additive for shootability and lifespan
• Half-size heavy — loads fast-action rods at real fishing distances
• Moderate & cold climate coating, braided multifilament core

Free spooling with in-store pickup — and if you're not sure whether the MPX or Infinity taper suits your rod and water, call the shop. Recommending the right line is kind of our thing.
