Sci Angler Amplitude Smooth Infinity Taper Floating Fly Line
The Amplitude Smooth Infinity 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: there is no end to what you’ll be able to do with it.

Abigail Walker –
I’ve tried several fly lines before, but the Amplitude Smooth Infinity stands out. It casts smoothly and handles both dry flies and streamers without tangles. The drag reduction makes a noticeable difference in long casts. I use it for trout and steelhead and feel more confident in my fishing.
Bella Ross –
The durability is impressive. After several seasons of use in different water conditions, the line still performs as well as new. The mending is smooth and the front taper helps with accuracy when targeting deeper water.
Donna Hunter –
Great for all-around use. I use it in both still waters and moving streams. The line feels responsive and doesn’t drag during casting. A bit heavier than expected, but that suits my fishing style.
Natalie Martin –
I switched from a traditional line and noticed a big improvement in casting distance and control. The smoothness and consistency make it easier to manage in windy conditions. Highly recommend for serious freshwater anglers.
