Roboworm's Straight Tail Worm is a terrific finesse bait when tough, crowded conditions are present. Super sensitive, these baits give a ton of action with the slightest movement. Straight Tail worms incorporate Robo's Salt Release System- which makes them heavier when you start fishing, and lets you know when the salt is running out and it's time to change worms. The Salt release system also gives a burst of salt when a fish strikes- which makes them hold on longer-for a better hook up.
