Using the Same Rig Everywhere
A running sinker may suit calm water but become difficult to control in stronger current. A light leader may work in clean surf but provide insufficient abrasion resistance around rocks and reef. Match the rig to the ground and water movement rather than using one setup everywhere.
Overbuilding the Rig
Heavier leaders provide additional strength and abrasion resistance, but unnecessary diameter and stiffness can reduce bait movement and make the leader more noticeable to line-shy fish, particularly in calm or clear water.
Using Hook Spacing That Does Not Match the Bait
If the hooks are too close together or too far apart for the bait, the bait may bunch, fold or leave the hooks poorly positioned. Adjust hook spacing to the bait rather than forcing every bait onto the same layout.
Using the Wrong Sinker Arrangement
A running sinker reduces resistance in calm conditions, while a paternoster provides greater bait control in current and deeper water. Choosing the wrong arrangement can leave the bait drifting, tangling or sitting in the wrong position.
Rigging the Bait Poorly
A bait that is not secured straight can spin or tumble during casting, descent or water movement. Correct bait position begins with matching the rig and hook layout to the bait being used.

Correcting these issues can improve how the bait behaves without changing bait type or fishing location.
