Which type of salmon fishing line you use on your fishing trip will often mean the difference between a successful day and one filled with a lot of snags, rats-nests and frustration. The right salmon fishing line will often be determined by the type of salmon you are going to be targetting during the day; there are specialty lines designed specifically for certain types of fishing conditions, and even standard lines will have varying results depending on the water you are fishing in.
First of all, it is important to understand the different construction materials used in different types of line. Species, depth of presentation, type of lure, size of lure all have a bearing on what type of materials you should be using. If you intend on trolling a spoon or heavier lure's you want to have a line with some give so you don't rip the lure out of the Salmons mouth and damage it. Monofilament has always been, and continues to be, the most popular choice among all anglers (those fishing for salmon included), at least as far as the bulk of purchases. Despite the steady sales in monofilament line, most people who fish will tell you that monofilament remains popular only because it is cheaper than other materials; one strand is not difficult to manufacture. A much more desirable type of salmon fishing line is that made from fluorocarbon. Fluorocarbon line is much stronger than nylon monofilament due to its complex structure (it is also often used in combination with copolymers). Most importantly to salmon fishers, especially those mooching or drift fishing, is the fact that fluorocarbon reflects light in much the same way as water, and is therefore much more difficult for a salmon to see. This is particularly important when considering leader material for your set up.
Tip: at the end of each season spool your salmon fishing line onto another vacant spool (preferably something large) using an electric drill to do the work if you don't have a winder. This will help the line with "memory" so that it's not all coiled up and easy to work with for the next season. Also if you do this you can usually get another season out of your line becuase when you spool it back onto your reel, it will be going on backwards. In other words, the line you'll be using will probably be untouched line that was always spooled up on the reel and never casted or run!
After test fishing this line for 3 seasons I’m a convert, and Suffix Performance Braid has become my favorite salmon fishing line. Here’s why: like other super braid lines, Performance Braid casts well, has good sensitivity, and limited stretch. Less line tangling, more consistent strength, and quieter when fishing, are qualities Ive found superior in Performance Braid. This is the primary line guests fish for salmon on my guide boat when casting lures with spinning reels, or when drift fishing bait, either along bottom, or under bobbers.
