A heavy sliding sinker for deep water and hard tide.
Six ounces is what a substantial live bait needs in a deep pass on a big moon, or nearshore where current is genuinely running.
The sliding design still matters. Line runs free through the sinker, so a fish taking the bait feels line rather than six ounces of lead and does not drop it before you come tight.
The egg shape rolls over rock and shell instead of wedging.
