The Keitech Flex Chunk 3 Medium in the #407T Delta Craw pattern is a high-performance jig trailer engineered to provide the perfect balance of volume, vibration, and visual realism. Written by Gerrys Fishing, this description details how the 3 Medium size bridges the gap between finesse micro-trailers and bulkier creature baits, making it a go-to choice for targeting big perch, zander, and pike in varied water conditions.

Key Features & Design Performance

• High-Torque Flex Claws: The signature feature of the Flex Chunk 3 is its oversized, curved C-shaped claws. These appendages are specially engineered to catch water and create a wide, rhythmic thumping pulse. Unlike flatter trailers that merely shimmer, the Flex Chunk creates a noticeable vibration that draws strikes from predators that rely heavily on their lateral line to track prey.

• Dual-Injection Buoyancy Matrix: Keitechs dual-injection process uses a buoyant, unsalted top section to keep the claws in a natural defensive posture, while the salted belly adds the necessary weight for accurate casting and a stable, horizontal swimming profile.

• Flat-Back Geometry: The top side of the trailer is completely flat, allowing it to sit flush against the underside of a jig heads hook shank. This ensures the trailer is perfectly streamlined, preventing the spinning or twisting that can occur with improperly rigged trailers, and providing a clean, cohesive silhouette that predators find more realistic.

• Delta Craw Pattern (#407T): This specific color is a masterclass in imitation. The mottled brown-and-orange finish provides an earthy, organic look that excels in clear to stained water, while the fine gold flecks mimic the light-reflecting chitin of a live crayfish.

Examples of Where to Use It

• Specimen Perch Search Fishing: Pair the 3 Flex Chunk with a 7g or 10g football jig or bladed jig. Its aggressive thumping action is ideal for covering water and triggering the predatory instinct of large, territorial perch.

• River Zander Drops: Perfect for use on jig heads (4g10g) in river channels. When zander are hugging the bottom, the buoyant claws float upward during the pause, creating a static, high-attraction target that is extremely effective in slow-to-moderate currents.

• Weed-Edge Prospecting: The robust 3 size is large enough to push through sparse weed growth. It serves as an excellent trailer for finesse jigs being worked along the edges of reed beds or lily pads, where pike and perch wait to ambush passing prey.

Pro Tip

The Defensive Flee Retrieve: When working the Flex Chunk on a jig, use a drag-and-pause cadence. Drag the jig 3 feet across the bottom, then stop abruptly for 3 seconds. The buoyant claws of the 3 Flex Chunk will float up into a claws-up defensive posture, while the jig head stays on the floor. This pause is the moment most specimen predators commit; the bait looks exactly like a crayfish that has just stopped to challenge an intruder.

Frequently Asked Questions

Which jig head matches best with the 3 Flex Chunk?

For the 3 version, we recommend a #1/0 or #2/0 hook on a finesse jig, football head, or bladed jig. The hook size is perfect for ensuring the trailer is securely held but remains flexible enough to allow the claws to move freely.

How does the 3 Medium differ from the Small 2 version?

The 2 version is designed for micro-jigging and situations where a tiny, subtle profile is needed. The 3 Medium provides a larger, more substantial meal that displaces more water and creates a louder acoustic thump, making it the better choice when you are targeting larger predators or fishing in water with lower clarity.

Does the Delta Craw color hold its finish?

Yes. The #407T Delta Craw is not a surface-painted color; it is a molded-in coloration process. The contrast, mottling, and fleck density remain consistent throughout the entire life of the bait, ensuring it looks just as effective after five catches as it does fresh out of the pack.
