Jigheads come in different weights for a good reason. A 1/16-ounce is a good all-around size because it has a slow fall yet enough weight to work when water is still or has a little current and in light wind conditions.
A lighter 1/32-ounce is good for calm days, in shallow water, when crappie will only take a slow fall and to stay in the strike zone a long time when casting or shooting docks.
A 1/8 or heavier jig may be required to get down to deep water or in windy conditions. It can also be cast a long distance but requires a moderate speed retrieve to keep it up in the water.
