Chloe James –
I’ve used several fly lines over the years, but the Amplitude Smooth MPX is by far the most responsive. The casting feel is smooth and precise, especially in windy conditions. The AST Plus additive really helps with shooting and keeps the line from fraying. Great for small fish like trout and panfish.
Amelia Berry –
The presentation is noticeably better than my previous line. The front-heavy design helps with accuracy and keeps the line from bouncing. I’ve been using it for bass and carp fishing and it’s proven reliable in different water conditions.
Steven Nash –
Solid performance overall. The drag reduction makes a difference when casting long distances. A bit heavier than I expected, but that’s probably due to the front mass. Works well in still waters and small streams.
