Another suggestion would be to pick up a spool of Seaguar AbrazX. As the name suggests it resists the wear and tear that dragging line "sideways" (down to the release clip), as well as the wear some clips can put on your line. My setups (rods/reels) are on the lighter side for most chasing salmon (10 lb line), so it's important for me to have a line that's more "durable"; I used to have to strip lengths of mono after the 2nd or 3rd trip (depending on how long each trolling time was). Obviously I don't pull flashers or use divers with this setup. It's a spoon and plug application. An increase in pound test would be obvious with dragging heavier/more resistant setups.
So far, this line has trolled two year (and next year I'll probably simple reverse the line on my spools and push the third year with it). Also, there's no need to add a leader since this is a fluorocarbon line. (That being said, ....you may eventually want to add a fluorocarbon leader in clearer water like G. Bay, as the this material -- fluorocarbon -- will get marked up from fish, landing net, boat floor, etc. and lose it's invisibility.
Just another option to consider.....
