Premier Tackle Insight

Choosing a versatile fly line can simplify your setup when you fish different techniques throughout the day. The Amplitude Smooth Infinity is designed to deliver streamers with power while retaining the control needed for dry-fly presentations.

Its extended head is particularly useful when making longer casts or managing line across current seams. The half-size-heavy design can help load faster-action rods at shorter distances, which is useful when fishing situations require quick casts. However, the way a line feels depends on your rod action, casting style, fly size, and how much line you carry in the air.

For anglers who want one floating line for a wide variety of freshwater situations, the Amplitude Smooth Infinity is a practical all-around option.
