This line performs exceptionally well in stillwater conditions. The seamless density transition keeps the fly steady and under the surface chop. The textured markers help with line positioning. I’ve used it for several days and it hasn’t lost any strength or flexibility.

The AST Plus additive makes a noticeable difference in casting. It’s easier to shoot and the line stays smooth even after repeated use. The 10 and 20-foot markers are very helpful for tracking line depth.

Good for intermediate to deep water fishing. The sink rate is consistent and the line doesn’t tangle. A bit heavier than expected, but that helps with long leaders and casting distance.
