A full pound of sliding lead. This is extreme-depth and heavy-current territory, where a big live bait would swim anything lighter clean off the spot.
Even at sixteen ounces the sliding design earns its place — a fish picking up the bait feels line running through the sinker rather than a pound of dead weight, and does not drop it before you come tight.
The egg shape rolls over rock and reef rather than wedging, which saves rigs on hard bottom where you can least afford to lose them.
