I lost one today well into the teens...It was after 10-15 mins of pain. Big hot fish in -5C temps with driving snow squalls and big giant water is not for everyone. I thought long and hard about chasing this fish but there really wasn't any real estate left. I stood my ground and after what seemed an eternity I had to clamp down. There was a fraction of a second where I actually thought I might turn this fish...That was followed by a sudden moment of silence...the GLX unloaded. It was actually a relief...My hands were frozen to the point of intense pain and my shoulders were aching. He won...got the better of a fresh 8lb flouro tippet. Insane!!!!
