Ball sinkers are popular for running sinker rigs, where the main line is
threaded through the sinker and left unattached, so it can move more freely.
They are often positioned either running directly to the hook, or restricted
to running along the main line above a swivel connection.
Ball sinkers are ideal when fishing current in fresh or saltwater when you
want your bait rig to move around, covering more area, but while keeping the
bait near the bottom.
