Designed specially for fishing in fast-running water. Elongated olive-shaped vane with an angle of rotation of 30º. The elongated vane design and the wight of the SPARK mena that it maintains constant rotation in strong currents. Small variations arise due to line speed. The Spark has a wide speed range, wich makes for good performance in counter-current fishing. Recommended for strong currents in swift-flowing and deep water. Good results with predators that do not usually react to bait.
