Tracey Cameron –
Used this leader on a trout stream and noticed a big difference in how the line disappeared underwater. The fish were more responsive and I caught several trout without any line breaks. Very reliable in rocky areas.
Carol Lyman –
The 4 lb line is thin and strong. It sank quickly and didn’t show up in the water. I’ve used it for steelhead and it held up well during aggressive runs.
Rebecca Murray –
Good abrasion resistance. A bit harder to tie knots than monofilament, but once adjusted, it works well. Sinks faster than regular line, which helps in getting to the strike zone.
Jonathan Carr –
Fished in a cold mountain stream and the line stayed invisible. No fish were spooked by the line. It held up during a long session with no breaks.
