In this guide, we’ll break down the key features of the **Amplitude Smooth Infinity** and help you decide if it’s the perfect match for your fishing style.
## **1. Understanding the Technology Behind the Line**
The **Amplitude Smooth Infinity** is built on Scientific Anglers’ advanced **AST (Advanced Shooting Technology) platform**, which enhances casting distance and accuracy. Here’s what sets it apart:

## **2. Choosing the Right Weight and Taper**
Fly lines come in different weights (1-15), and selecting the correct one depends on your rod and fishing conditions.
– **For freshwater trout fishing (3-6 weight rods)**, the **Amplitude Smooth Infinity in WF (Weight Forward) taper** is ideal for delicate dry fly presentations.
– **For saltwater or larger species (7-10 weight rods)**, the **Infinity line’s aggressive front taper** helps turn over big flies with ease.
