If you’re anything like us, the allure of big fish and big rivers is intoxicating. That’s precisely why we created the Amplitude Smooth Anadro/Nymph. Designed with line control in mind, its extended rear taper allows you to cast a mile, mend with authority, and turn over nearly any rig imaginable—from dredging double nymphs to larger dry-dropper concoctions. Steelhead, salmon, and trout won’t know what hit them.

This fly line performs exceptionally well in long casts. The smoothness and reduced drag make it easy to mend and control, especially when using double nymphs. I’ve fished it in rivers with strong currents and it held up well under pressure.
Ryan Welch –
The AST Plus additive gives it a noticeably smoother cast. I can now cast over a mile with minimal effort and the line doesn’t fray even after repeated use. Great for both dry flies and nymphing.
Pippa Rees –
Solid performance in the field. The durability is impressive, and the rear taper helps with rig turnover. A bit more expensive than standard lines, but worth it for serious anglers.

I’ve used this line on steelhead and trout rivers. It handles heavy strikes without breaking and maintains a clean cast. The mending is smooth and precise, which helps when fishing in tight spaces.
