Used this leader wire on a recent offshore trip with large predatory fish. It held up well under heavy bites and didn’t snap even when the fish hit hard against rocks. The nylon coating stayed intact and the wire felt smooth to handle. Very reliable for tough conditions.

Great for setting up heavy rigs. The flexibility is noticeable compared to solid wire, and it doesn’t kink easily. I’ve used it in both saltwater and freshwater environments with no issues so far.

Solid performance in rocky areas. A bit stiff when first pulled, but settles into a good flex. The coating prevents rust and looks clean when attached to the main line.
