Scientific Angler Amplitude Smooth Anadro

This is our top pick for a nymphing line on the Bighorn River. 

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.
