Used this line for bonefish and tarpon in the mangroves. The head cuts through wind easily and the line doesn’t tangle. It’s much smoother than my old line and holds up well after a full day of fishing.
Adam Coleman –
Fished with this line during a permit season. The drag reduction made a big difference in casting accuracy. The line stayed intact even in rough conditions. Highly recommended for coastal fly fishing.

Great performance in light wind. The shooting ability is noticeably better than standard lines. A bit expensive, but worth it for the durability and smoothness.
