Leader material: weaker link or stronger

A leader is a short length at the business end, and it is the only part of a setup deliberately made unlike everything else. In two opposite directions at that.

Two opposite jobs

The first arrangement: the leader is made weaker than the main line. Then on a solid snag it is the leader that goes, and the rig and main line stay with you. The loss comes down to a hook rather than the whole set-up.

The second is the reverse: the leader is made stronger when the threat is not a snag but teeth. A pike cuts through ordinary line regardless of its breaking strain, and what saves you there is material, not diameter.

Materials for the second job

Against teeth you use what cannot be cut: steel traces, titanium, and multi-strand materials in a coating. They differ in stiffness and in how they behave after a load — steel often stays kinked, titanium springs back.

The price is visibility and an effect on the lure's action: a stiff trace changes how it moves, and not always for the better.

Materials for the first job

Where teeth are not expected, the leader is fluorocarbon or plain nylon of a finer diameter. The choice here is between invisibility and cost: fluorocarbon shows less underwater, nylon is cheaper and softer.

What matters is that the leader be a deliberately weaker link, not accidentally the same as the main line: then on a snag whatever fails first goes, and that cannot be predicted.

How a leader is attached

A leader joins the main line either by a knot or by hardware — a swivel and a clip. A swivel also guards against line twist when the lure spins on the retrieve.

Hardware is a link too, and it also has to hold: a cheap clip opens before the line breaks, and then the whole „weaker leader" idea decides nothing. The knot-only version is slimmer and passes the guides better.

Leader length is a choice as well

A long leader hides the setup better but affects presentation more and tangles more often. A short one alters the lure's action less noticeably but leaves the main line closer to teeth and to the bottom.

There is no universal answer — it depends on what exactly you are guarding against.
