Dominic Clarkson –
Used this shock leader on a recent trip to a deep lake with heavy cover. The line stayed invisible and held up well under pressure. It didn’t snap when a large bass took the bait. The knot strength was excellent and the abrasion resistance kept it from fraying.
Jonathan Hudson –
Fished with a 5 lb test on a rocky shoreline. The line performed well and stayed intact even after a strong pull. It’s more visible than I expected, but still better than monofilament in murky water.
Tim Hardacre –
Great value for the performance. The triple-resin processing makes it durable and strong. I’ve used it with both braided and monofilament lines. It’s reliable and doesn’t stretch much under load.
