Mary James –
This line casts smoothly and reaches farther than I expected. The sink rate is consistent, and the fly stays on target. Great for long-distance casting in open water.
Diana Skinner –
I’ve used it in both still and moving water. The turnover is quick and the line holds its shape well. A solid choice for serious fly fishing.
Samantha Hughes –
The braided core gives it a strong feel and it doesn’t tangle easily. I noticed a noticeable improvement in accuracy when casting over 50 feet.
