I am super impressed with Gamma Copolymer fishing line. I'm using 10lb fishing docks for largemouths and I've caught a ton of big fish without any breakoffs. I need to retie, but even with some abrasion marks the line continues to hold up. My clients this week got to experience this first hand when he set the hook into a 3+ pound largemouth. The fish got wrapped on a log and he was able to keep the fish on with out the line breaking and we landed that fish. It was a beauty!
