When a choice exists in the number of balance ropes to be used, we would invariably recommend the largest size and the smallest number compatible with handling. Larger ropes are less easily damaged by spillage, they involve less inspection and maintenance, they are more economic in themselves and their attachments, and there is less risk of fouling with fewer ropes.
