XX Strong. Saltwater use with up to 50 pound test line. Lighter hook encourages rigged live baits to swim more naturally. Select sizes are available in ringed models. Super strong, welded rings in the eye of each hook reduces stress on the hook, making overall unit stronger. Ringed hooks also allow live bait to swim more naturally, and once hooked up, the hook pivoting on the ring tends to wear less of a hole in an active fishes mouth.
