I haven't used lc-13 since I was obsessed with big chinook salmon on a fly out west. Once the coho started busting around the boat I'd go back to the intermediate and never did quite untangle the total unknown realm of big king salmon on the fly rod although I did get one a few and one was in the mid-to-high 30 pound class. They start out hunting in 20-40 feet of water at dawn, most in 60-90 feet, then by 10am they are from 150-200 feet down in the 600-1000 foot depths of the Straits of Juan DeFuca. With the tide rips running hard LC made a big difference when fishing more than 20-30 feet down there.
Probably because I fish primarily from shore I don't need LC13 and I use zero lines with loops for stripers for the reasons stated above (just personal preference).
It just came up as a way to get cod on a fly! }>
