Light tapered lead for inshore and shallow structure fishing.
An ounce is inshore weight — enough to hold a bait near a dock piling, a bridge fender or a shallow rock pile without anchoring it.
The bank taper still matters at this size. Fishing around pilings and oyster means constant contact with things that grab lead, and a shape that slides free is the difference between fishing and re-rigging.
The 5lb box is far cheaper per sinker than packs, and around structure you will go through them.
