The Gary Yamamoto Fat Senko 4" maintains a length of 10.2 cm while increasing the diameter of the classic 4" Senko by 20%. This gives it more volume and weight in a compact package. Its oscillating descent works particularly well when fished without a weight or on a wacky rig. Pack of 10 lures.
The 4" Fat Senko meets the need for a short worm that maintains a strong presence in the water. The thickened body adds mass without requiring a longer lure; the action remains that of a Senko, which wiggles as it sinks.
Without additional weight, the body’s weight alone is enough to make the rig sink. The descent then becomes a fishing phase in its own right. When rigged wacky-style, the hook is placed in the middle of the worm: both ends remain free to move around the attachment point.
A small jig head or a Ned rig also allows it to be used near the bottom.
