The B5 Line Thru Swimbaits feature a hard thumping tail and body rolling action thanks to the internal weight system. To fish one, just pass your line through the bait, tie on the included Gamakatsu treble hook, and insert one of the trebles into the body of the bait to hold it in place. For optimal results, fish it slow. While you’re fighting a fish, the bait will slide up your line so that the fish can’t use it as leverage to throw the hook.
