I have used white braided nylon rope purchased at the local hardware store for 
just this purpose. That rope has been up for 12 years in the high-UV Colorado 
environment. To date, it is not quite as flexible as it orginally was, but 
runs just fine through the garden-variety pulleys that I installed at the same 
time. I'm not sure I understand the concern about special pulleys and rope in 
what is a very light load application.
