Power Meets Finesse—Now in a Silent, Slick Package
The Amplitude Smooth MPX is a best-in-class all-purpose fly line designed to do everything a trout angler could ask for—and do it quietly. Built a half-size heavy with a front-biased taper, it loads modern fast-action rods with authority while still allowing for delicate dry fly presentations when it counts.
This line features SA’s AST Plus slickness additive, making it one of the slickest, longest-lasting coatings on the market—but in a smooth finish that slides silently through guides (no textured “zip” like the original Amplitude series). Whether you’re throwing hoppers, chucking nymph rigs, or punching into wind, MPX handles it.

The line casts smoothly and feels great in the hand. I’ve used it for both dry flies and nymphs, and it handles wind well without tugging or snagging. The silent glide through the guides is noticeable and a big improvement over older lines.

Perfect for my fast-action rod. The front-biased taper gives me good power when needed, but I can still present dry flies with precision. The slick finish reduces friction and makes casting feel effortless.
Eric Mackay –
I appreciate the all-around performance. It works well in both still and moving water. A bit heavier than I expected, but that’s fine for my rod setup. No issues with wear after several weeks of use.

The quiet cast is a game-changer. I can now fish in more sensitive areas without worrying about noise disturbing the fish. The line stays clean and doesn’t build up residue easily.
