WHERE TO BUY ROPE
I am constantly asked where I got my rope from. I bought mine from the manufacturer Whittam Ropes in Melbourne Australia. You need an Australian Business Number to purchase from them. You can also get rope from cams cords in Brisbane. I have put some links to other places below as well, since most of my enquiries come from other countries.
