When fishing with jerkbaits for muskie, using a stiff wire leader is always a good idea, as stiff wire provides security against bite-offs and improves lure presentation. When casting with bucktail spinners or trolling with crankbaits, you can instead use a heavy fluorocarbon leader.
A wire leader is needed when targeting predatory freshwater or saltwater fish with sharp teeth. As such species will have no problem biting through conventional fishing line, using a wire leader will effectively ensure that you won’t lose your hook, lure, or fish.
When it comes to wire leaders for pike, your best choice is leaders that are made of multi-strand titanium or stainless steel wire. These materials are extremely strong, smooth, and flexible, allowing for an optimal bait and lure presentation.
For walleye per se, you do not need to use a steel leader at all, as they won’t be able to bite through your mainline. However, if the water you are fishing in contains pike or muskies, you can use a 10-15lb fluorocarbon leader instead of steel, in order to prevent bite-offs.
