Single assist hook using spear hook (SH-20). Since it uses an assist line with a moderately firm fluoro, it is also characterized by less clinging to the jig during jerk and less power loss during hooking. It hangs quickly with a sharp hook point, and it is very hard to get caught even after hooking. It is very effective when you want to make the best use of the original movement of the jig and jerk quickly and trickily to finish the greenery.
