FAQ
What makes the AST PLUS slickness additive different from other line additives?
The AST PLUS additive reduces friction during casting, allowing for longer and more consistent casts while improving durability and performance over time.
How does the floating texture on the tip section benefit fishing?
The floating texture helps keep dry flies afloat longer, improving their natural movement and increasing the chances of attracting fish.
Is this line suitable for use with small dry flies?
Yes, it is specifically designed as a true-to-grain-weight line for casting small dry flies to picky risers.

This fly line performs exceptionally well on long casts with dry flies. The floating texture keeps the flies up longer, and the shooting texture makes a noticeable difference in distance and accuracy. I’ve used it on glass rods and it handles well in windy conditions.

Great for medium to long casts. The line feels smooth and doesn’t tangle easily. The tip section stays buoyant, which helps with dry fly presentations. A bit more expensive, but worth it for the performance.

I’ve switched from a standard fly line to the Amplitude Textured model and see a clear improvement in casting distance and consistency. The AST PLUS additive really makes a difference in how it glides through the air.

Works well with small nymphs and dry flies. The elongated front taper allows for delicate presentations, which is perfect for fishing in slow-moving streams. No issues with line wear after several uses.
