Amplitude Infinity Smooth Fly Line
The Amplitude Smooth series of lines are, simply put, the highest-performance smooth fly lines in the world. With up to five times less drag and eight times the durability of traditional lines, this will change the way you look at fly line performance.
The conventional wisdom in fly fishing is that there’s no such thing as a “do it all” freshwater line. We have something to say about that. The Amplitude Smooth Infinity has the power to bomb out streamers, yet retains delicacy for dry flies. It mends like an absolute dream, and delivers flies at all distances. Built a half-size heavy, with a long head and substantial front taper, it’s perfect for everything from trout and panfish to pike and steelhead. There’s a reason we call it the Infinity.

This line has transformed my fishing experience. I use it for both dry flies and streamers, and the mending is smooth and consistent. It handles wind well and casts farther than my previous line without losing accuracy.
Sean Turner –
Great balance between power and sensitivity. I’ve fished it in streams and lakes, and it performs well with both small trout and larger pike. The drag reduction makes a noticeable difference in casting speed and control.
Yvonne Hardacre –
Solid performance overall. The line feels smooth and doesn’t tangle easily. I noticed less drag when casting in fast-moving water, which helps with precision.
