Formula X is the same basic construction as Formuline but has a normal 8 plait finish ( not as smooth as Formuline) which makes it perfect for those that want a very tough rope but one which you can grip by hand or use in a North or Duotone Power XT ratchet style extension (the rope looks exactly the same as the original white North Rope)
