Somebody asked this the other day, so here is a quick take on when to use braid, and when to use monofilament lines.
Trolling and casting are the main times to use mono types of line. The reasoning is that monofilament will stretch to a certain point, thus not allowing the hooks to get ripped out of a fish’s mouth. Is it true, yes to a certain extent, specially when casting for walleye. When it comes to trolling, mono also will provide a sort of balance between the strike and hook-up. This really is true when long lining behind the boat with the rod in hand even though the rod tip will provide some cushion. This is less true when it comes to running planer boards because the board will act as a snubber of sorts. What is a snubber? It is a salmon and trout tool that works as a shock absorber when a lure is hit by the fish.
What casting takes place on Lake Erie? Long before trolling ruled the scene, people would drift their boats and cast numerous types of lures in order to catch walleye. One of my favorites was called the Nugget, but we called them Golden Nuggets because that was the finish most commonly used. Of course the tried and true Erie Dearie is still being used today, but I loved those Nuggets back in the day. Lately the Weapon, or mayfly rig has been king when it comes to casting for walleye on the big water. Basically a Carolina Rig these baits can be counted down in water column and then retrieved or dragged along the bottom to catch fish.
Jigging, and rigging falls solely under the category of running braided lines. Non-stretch lines rule this type of fishing because the hookset while vertical jigging is everything. Braid will help you cut the current while on the bite will drive the hook home. When rigging with plastics or livebait, the line will allow you take up any slack quickly and ensuring the hook gets buried on the bite. How does rigging apply to walleye on Erie, this inland lake application has more use on the big lake than you think. In the spring it can be applied to popping hair jigs off the bottom when drifting the boat over a flat or numerous dumping grounds here in Michigan waters. This could also be applied to dragging weights on the bottom with a floating rig or short crawler harness.
