Lupa Gear offers round Tungsten Ball Jigheads alongside dedicated Ned heads. The difference is more than shape: Tungsten Ned Jigheads Matt Black combine a tungsten head with a Mustad hook, whereas Ned Resin Jigheads Matt Black have a resin head. These two Ned versions should therefore not be treated as the same material.
Let your soft plastic determine hook size
Hold the hook beside the lure before rigging. Leave enough hook point exposed without pinning the moving part of the lure with an overly long shank. Then choose head weight for depth and current. Tungsten is denser than lead, allowing a more compact head at the same weight. Compare material, hook size and weight across Lupa Gear heads; grams alone do not tell you how the rig fits your lure.
