This line casts smoothly and feels much lighter than others I’ve used. The high-contrast sighter helps when fighting fish on long runs. Great for bonefish and small saltwater species in warm climates.
Sonia Underwood –
The drag reduction is noticeable. I’ve been using it for several weeks in the Caribbean and it holds up well under heavy use. The AST Plus additive makes it glide through the water easily.
Sally North –
Solid performance with good durability. The taper allows for long leader casts without losing control. A bit more expensive, but worth it for the performance.

Tropi-Core technology works perfectly in humid, warm conditions. No sagging or stiffness issues. The sighter is very helpful during long fights.
