When backslide set with an offset hook, the degree of freedom in eye position is low. The slide piercing can be moved back and forth by a dedicated worm keeper. By changing the eye position, the fulcrum and center of gravity of the rig have changed, making it easier to adjust the "angle" and "speed" of the fall. Using a nail sinker allows for further fine-tuning.

The hook adopts a pierced hook TC, which demonstrates high hooking performance even in situations where hooking power is not sufficiently transmitted, such as over the cover or in situations where the hooking power is not sufficiently transmitted.
