At low speeds, the body undulates; as the current or retrieve speed increases, the rolling motion becomes more noticeable. Vary the tension without resorting to frequent hard tugs: the joint is already working with a steady retrieve.
When casting, the avalanche lock prevents the tail from folding back freely. The small size remains well-suited for shorelines and narrow currents. Control the descent before retrieving, and make sure the lure and its hooks are appropriate for the fishing spot.
