I'm just getting back into fly fishing after a nearly 30-year absence and was looking for a line that would enhance the performance of my relatively inexpensive 5 and 6-weight rods. Upon the recommendation of several people, included Sunrise's Ryan Barba, I purchased SA's Amplitude Smooth Infinity lines in both 5 and 6 weights. Although I'm no expert fly caster, I can say these lines shoot through the guides with ease. I've been able to make good casts at short, intermediate and longer distances. I just recently fished the Colorado River tailwater below Lake Powell using my 5-weight with a double nymph rig, a fairly heavy split shot, a foam indicator and, counting the tippet extensions, about 12 feet of leader. I really liked the way I could feel my rod load on the backcast making it easy to time my forward stroke. Another angler who was watching me cast commented I was throwing a very tight loop. All I know the line was laying out straight and landing where I was aiming. It cast very well into the wind. It was very easy to obtain long drag-free drifts. The line didn't seem to belly downstream right away, and when it did a quick upstream flip of the rod was all that was needed for a nice mend. I've also practiced casting dry flies on a local city park pond here in Phoenix, and I'm able to drop a small dry very gently on the surface. I suspect this line would work well with streamers and even wind resistant bass bugs.
Being a half-weight size heavier than most comparable lines, I believe this line would work best on medium fast to fast action rods. It would seem to be an excellent line for beginning and intermediate casters, however I suspect experts would enjoy fishing it. I would call it the .30/06 of fly lines as it appears to perform many tasks extremely well. I would like to thank Ryan and the others for recommending it.
