Reducing it to one guy pulling a cord will make our lives much easier. With space being a premium on our bridge, we'll be able to use the curved turbolift approach along with the traverse lines, and voila.
Funny you should mention the copiers considering that's what I do for a living. That particular kind of cord is generally a metal one, and that might be better than the draw string from the traverse blinds. I think a chain would be too noisy, though.
