SCIENTIFIC ANGLERS AMPLITUDE SMOOTH INFINITY FLY LINE
Scientific Anglers Amplitude Smooth Infinity Fly Line, Winner of the coveted Best Freshwater Fly Line Award at IFTD. The conventional wisdom in fly fishing is that there’s no such thing as a “do it all” freshwater line. Scientific Anglers has 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 anyd 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. 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.

Great fly line! ★ ★ ★ ★ ★ 5

Really like this line and most of the SA lines. Got it for my 4wt Echo carbon XL. Casts great and is not too heavy but also heavy enough to load the rod and be easy to cast. Definitely recommend this line.

Clay from RFR talked me into it and I could not be happier with this purchase. Using it on a 376 Lift with an Ion reel. I wanted something to fish throughout the smokies. Casts like I know what I'm doing out there! I have the precision to place flies where I need them in tight spots, and I get better distance than I had imagined possible on those wider stretches of river. This is the second SA line I've used (MPX being the first). I cannot see myself going back to another line at this point. Great line, even better Customer Service! I love everything about RFR.

Best Fly Line ★ ★ ★ ★ ★ 5

S.A. fly lines are one of the best over all . They have a coating that helps keep the line moving and casting long distances . Also , last longer than some brands .

I generally switch back and forth between Rio and SA fly line. I've used less expensive fly line in the past and usually regret and wonder why I bought it. SA and Rio are more expensive lines but I have found they are worth it. This SA amplitude infinity fly line is the bomb. I purchased the 6 wt line and it cast beautifully and it will be a nice all around line for me. I think I will be hooked on SA line a little more now.

Solid all purpose line ★ ★ ★ ★ ★ 5

I have the 6 wt. If you are looking for a solid general purpose line you should look no further. This is a great casting line that can handle small dries to 3-4" sex dungeons.

I've been using Rio Gold on my 4, 5 and 6 weights for awhile but since trying this on my 5 I purchased for 4 and 6 weights as well. I still like the Rio and find it has a bit more finesse but this seems like it will hold up better and its smoothness helps generate line speed. Also slightly heavier than the Rio and helps to load rod just a bit faster. Highly recommend as an all around line.
