different rope sizes?

[fraxinus]

i got all visible creosote off the line. using hot water and a nylon brush, seems to have worked, there is no stiffness in the rope either (other than whats intended) so i think its ok on that front. and i do want a 12-13mm static line, but as it happens i have been left up the creek by a fella and now have a lot less work and a £450 debt to pay off and a lovely bout of medical probs, so it will just have to wait untill i'm clear again.
