A wacky rig hooks a stick bait through the middle. It falls flat, with both ends shaking.

For a 5 in. stick bait, use a #1 to 1/0 wacky or octopus hook, no weight. Slide an O-ring on first so the bait lasts longer.

It's a shallow, slow-fall rig. In deep water or wind, add a nail weight or switch to a neko rig. In thick cover, a Texas rig is safer.

Through the middle or an O-ring?

There are 2 ways to hook it.

Through the middle. Push the hook straight through the bait at its midpoint, across the body. It's fast and needs no extra parts. Soft stick baits tear, though, often after 1 or 2 fish.

O-ring. Slide a small rubber O-ring onto the bait to the midpoint. Then slip the hook under the ring, not through the plastic. The bait lasts far longer. A rigging tool makes the ring easy to put on.

Put the ring or hook a touch off center toward the thicker end if the bait falls tail-first. A true midpoint gives the most even fall.

Hook point direction: many anglers run the point toward the bait's head. Either way works. Be consistent so you know how it'll hang.

Hook size by bait length

Thicker baits need a bit more gap. A light-wire hook sets easily on spinning gear. A heavy-wire hook holds better around docks and wood.

Weedless wacky hooks have a thin wire or fiber guard over the point. They help around docks and sparse brush. See bass hooks by type for the details.

O-rings go on faster with a tool. A wacky rig tool with O-rings stretches the ring and slides it onto the bait in 1 push.

Weighted wacky

A nail weight pushed into the middle of the bait, next to the hook, makes it fall faster and level. It's still a wacky rig. It just gets down quicker.

Use 1/32 to 1/16 oz in 6 to 12 ft.

Some anglers use a small jig head with a wacky hook instead. Either way, the bait still falls flat.

Use it when fish sit deeper, or when wind puts a bow in the line and you lose feel with a weightless bait.

Neko rig

A neko rig puts the weight in 1 end. The bait stands up on the bottom, nose down, with the tail waving.

Sources differ on ring placement. Bassmaster describes a hook about 2/3 of the way up from the weighted head. USAngler puts the ring about 1/3 from the head. Try both. The farther from the head, the more the whole body moves.

Hook point up toward the tail helps the rig come through cover and hook fish on the drag.

How each version falls

The weightless wacky rig falls slowly and flat. Both ends shake. Many bites come before it hits the bottom.

The weighted wacky falls faster but still flat. You give up a little action for depth and control.

The neko falls head first. On the bottom, it stands up and wiggles when you shake the rod. It's a bottom rig, not a falling rig.

Fishing it

Cast near a target: a dock post, a laydown, a grass edge. Let it fall on slack line. Watch the line where it enters the water.

If the line jumps or swims off, reel down and set. If the bait hits bottom with no bite, lift it 1 or 2 ft and let it fall again.

For a neko, drag it slowly and shake the rod tip. Pause often.

Use a sweep hookset on light line. A hard jerk on 8 lb fluoro with a light-wire hook can break off.

Choosing the stick bait

"Senko" is a brand name, but many anglers use it for any soft stick bait. The rig works with most of them. A 5 in. senko-style stick worm is the usual size.

• Salt-heavy stick baits: sink on their own with no weight. Soft and lifelike, but they tear easily. O-rings help a lot.
• Firmer or elastomer stick baits: last much longer. Some float, so they may need a nail weight to sink.
• Ribbed or tapered stick baits: more movement on the fall, a bit less durable.

Length matters most for hook size. 4 in. for small fish and clear water. 5 in. as the all-round size. 6 in. or longer for bigger fish and dirtier water.

Colors are personal. Green pumpkin and watermelon shades are common picks in clear water. Darker colors stand out in stained water.

Seasons

Spring. Fish move shallow to spawn in 2 to 6 ft. A weightless wacky rig, cast past the bed and let fall, is a classic.

Summer. Fish hold in shade under docks and along grass edges. Skip a wacky rig under the dock. Go weighted on deeper edges.

Fall. Fish chase bait shallow. A wacky rig can work, but moving baits often cover more water.

Winter. Go to a neko on rock and gravel, slow and close to the bottom. 1/16 to 1/8 oz in 10 to 20 ft.

Skipping docks

Skipping sends the bait under a dock with a sidearm cast that bounces off the water. A wacky rig skips well because it's compact and has no weight to sink it fast.

Use spinning gear and 10 to 15 lb braid with a fluoro leader. A 1/0 weedless wacky hook helps on dock posts. Practice in open water first. Backlashes on spinning gear are less common than on a baitcaster.

Checking the rig

Look at the bait after every fish. A torn middle means it's time for a new bait or a new ring.

O-rings stretch and split over time. Swap any ring that slides along the bait. A loose ring lets the hook spin around, and the bait falls crooked.

On a neko, check that the nail weight hasn't backed out of the head. A drop of glue on the weight before you push it in helps.

Line choices

A 7 ft medium or medium-light spinning rod is common. Join braid to the leader with a double uni or FG.

Where it fits on the water

• Spawning flats in 2 to 5 ft, spring: weightless 5 in. stick bait on a #1 hook, O-ring.
• Docks in 4 to 10 ft: a 5 in. bait on a 1/0 weedless wacky hook. Skip it under the dock.
• Grass edges in summer, 6 to 10 ft: weighted wacky, 1/32 to 1/16 oz.
• Rock and gravel points, 8 to 20 ft: neko, 1/16 to 1/8 oz.
• Clear lakes, pressured fish: neko on 15 to 20 lb braid with a 6 to 10 lb fluoro leader.

Common mistakes

1. Hook through the plastic every time. Use O-rings and save baits.
2. Too heavy a weight. It kills the slow fall. Start at 1/32 oz.
3. Watching the rod, not the line. Bites show on the line first.
4. Neko point facing the head. It snags more. Turn it toward the tail.
5. Hard hookset on light line. Sweep instead.

When not to use a wacky rig

• Thick grass, mats or brush. The exposed hook snags. Use a Texas rig.
• Long, open flats. A Carolina rig covers more water.
• Catfish and bait rigs. See catfish rigs instead.
