Jig heads: the component that decides how your plastic behaves

What a jig head actually controls

It looks like a weight with a hook in it. It is doing three jobs, and getting any of them wrong spoils an otherwise good soft plastic.

1. Fall rate. Most soft-plastic bites happen on the drop, so the speed of that drop is the single most important variable you control. Heavier falls faster; slower gets more bites.

2. The angle the bait sits at. This is the eye position, and it is why different head shapes exist at all. A 60-degree eye stands a worm upright off the bottom; a 90-degree eye swims a body horizontally; a 30-degree eye drags nose-down.

3. Whether the plastic stays put. A bait keeper — a barb, a screw lock, or a moulded collar — is what stops the plastic sliding down the shank. Without one, a fifteen-cent head ruins a bait every two fish.

Weight by depth, not by fish

The rule that generalises across this whole site: use the lightest weight that still lets you feel the bottom. Adding weight is a response to losing contact, not to bigger fish.

Eye angle, and what each one is for

For a first selection, round heads for panfish and crappie and a few shakey heads for bass covers the great majority of soft-plastic fishing.

The bait keeper is worth paying for

This is where cheap heads cost you money rather than save it.

A plain hook shank with no keeper lets the plastic work its way down after a couple of fish. Once it has slipped, the bait hangs crooked, spins on the retrieve, and puts twist in your line — and you cannot see any of it happening.

A barb, collar or screw lock adds very little to the cost and roughly triples how many fish each soft plastic survives. Over a season that is a lot of plastic.

Painted or unpainted?

Mostly cosmetic and worth about thirty seconds of thought.

Painted heads help slightly in clear water where the head is visible, and matching the head to the body looks tidier. Unpainted lead heads catch fish perfectly well and cost less — Strike King publishes four per pack unpainted against three painted, which is the price difference expressed as quantity.

Where it does matter: a bright head on a natural body gives a fish something to aim at, which some anglers use deliberately as a strike trigger on crappie jigs.

What we would skip

Assorted jig head kits. They arrive with a spread of weights and hook sizes, most of which do not match the plastics you own. Buy two weights in the hook size your baits need.

Very cheap heads with soft hooks. The hook is the part you cannot inspect before buying and the part that fails on a good fish. A named hook — the Strike King heads publish a Gamakatsu — is a reasonable proxy for a hook that will hold.
