If you're using long bits of rope that aren't very close to the camera I'd 
recommend setting Rope_ShowFibres to 0 for those ropes because the 
transparency used to display the fibres has a big impact on render times and 
memory use. You only need Rope_ShowFibres set to 1 for those bits of rope 
that are close enough to the camera for the fibres to be visible and someone 
did comment that they thought the ropes looked better without the fibres 

Certainly for test renders it's better to set Rope_ShowFibres to 0.

That sounds terrific. I'd love to see how it looks when it's complete.
