A steady retrieve is enough to make it meander. Add a jerk to create a sudden swerve, then pause: the lure sinks while oscillating, which prolongs the presentation without moving forward quickly.
The pendulum joint keeps the sections aligned during the cast and works in conjunction with a weight transfer mechanism. The flexible TPE tail is replaced by the S model designed for the 128. Adjust the length of the pauses based on the available depth to keep the hooks off the bottom.
