What Line Should I Use?

Most, if not all, people who troll for walleye use a book that we refer to as “The Troller’s Bible”. No, it’s not a religious document, but it can give you that feeling of angels singing when the information held within its pages is utilized and you’re rewarded with a nice plump walleye tugging on the end of your line. 

The book I’m referring to is called “The Precision Trolling Book” by authors Mark Romanack, Dr. Steven Holt and Tom Irwin.

Back in 1990 these three gentlemen got together and created depth charts for just about every crankbait on the market today, using scuba diving tactics to gather the information. 

A depth chart tells you how much line you need out to get your lure to a specific depth and at what speed to achieve it.

The depth charts were created using a 10 pound monofilament line with a line diameter of .0134. I like to use a 14 pound test mono that has the same line diameter, but a stronger tensile strength. Due to my aversion of doing math in my head, this allows me to use the same charts without having to use the line conversions in the book.

A monofilament line will stretch while a braided line will never stretch. So, what’s the purpose of using a braided line over a mono line? The braided lines are much more abrasion resistant, stronger and have a smaller line diameter for the same pound test as a mono line. The smaller diameter will cut through the water easier, create less bow in the line and make your lure swim deeper with the same amount of line out as its mono counterpart.

As important as a well set drag is on a reel filled with mono line, it’s even more important when using a braided line. If a fish is fighting, and your drag is not set loose enough, it will rip the hook right out of its mouth with the braided line. Mono is a little more forgiving in that it will stretch and give you a chance to adjust your drag properly for the size of fish you are fighting before the fish can get away.

So, the most important lesson today is, utilize the depth charts, know where your lures are and always check your drags before you need them.
