As an expert in the product and industry, it is important to note that the Strike King Zero Stick Worm contains a high concentration of salt, resulting in a quick sinking action similar to other Senko Style baits. However, what sets the Zero apart is its use of Strike King’s revolutionary 3X plastics, ensuring exceptional durability. With this, you can fish all day without the need to constantly replace baits. In fact, the Zero outlasts 20-30 other stick baits.
