According to the strand constructions made up of wire rope, there are lots of different wire ropes. You, however, choose the right ropes in accordance with the use you want is more important.
A line should be selected that combines the proper attributes for mooring when reasonable flexibility and high MBL are priority requirements. The recommended construction is 6x36 or 6x41 (6x36 class) with the wires in each strand of equal lay and the stands of regular (ordinary) right hand lay.
Steel wire lines with and independent Wire Rope Core (IWRC) are strongly recommended over fibre core steel wire lines for several reasons. And IWRC steel wire line has a much greater resistance to crushing, higher MBL for a given diameter and greater strength retention when bent.
