I’ve used this line for several weeks on a quiet pond and it performs consistently. The sinking rate is just right for deep water fishing with streamers. The mid-length head gives me better control when casting in the wind.
Jasmine Cameron –
Great for stillwater fishing. It sinks smoothly and doesn’t tangle easily. The thin diameter helps it cut through light wind, which is a big plus in open areas.

Felt like a solid upgrade from my previous line. The sink rate is stable and the front welded loop is secure. I’ve used it with both streamers and wet flies with good results.
