I use 20 pound mainline and 15 pound flourocarbon lead for almost everything now on my pin. People may think it sounds overkill, but I land fish quickly and still get a hell of a good fight out of them without stressing them to the max. It gives me the ability to turn fish if they are trying to go where I don't want them to as well... can put the breaks on without having to worry about breaking off. The 15 pound flouro I use is around the same diameter as 10 pound test, so it doesn't spook fish.
I started running 20 pound main and 15 lead when I started fishing high gradient canyon rivers for steelhead which made me turn to heavier line so they didn't leave the run and go down cascades/waterfalls, etc. It seems to work well for springs too, allows me to move them off bottom, and some of the places I fish for them, it isn't possible to chase if they leave the run, so once again I can put the breaks on.
