Just bait size that does not choose rigs and situations. The complex body surface with irregularities on the antennae with different volumes creates slight vibrations during action. The four legs attached to the head generate a very small vibration while chewing water at the time of fall, and even in situations where you do not like stringing, you can surely make the fish use your mouth with no action. Slits have been placed to make it easier to set the jig head and offset hook.
