Modelers,
I did some very basic investigation on this topic. I had been using the 'fine' EZ-Line for rigging 1/72nd scale aircraft but it always looked heavy. I then started splitting it into halves or thirds if I could, to lighten it up. It still looked a bit overdone. I then found nichrome wire in very fine gauges. I didn't have much success with it as it's very shiny and I couldn't find an easy solution to dull it up. Just recently, I found Infini rigging line. It's lycra based like EZ-Line but comes in a multitude of sizes over their ship and aero lines. I decided to put together a quick reference for my own memory so I don't use the wrong size in whatever scale I'm working in. I thought others may benefit from this so please see the attached .pdf if you're interested. Again, this is just a generalization to try and get close to scale rigging. I will be trying it out on a 1/72nd scale Voisin to see what it looks like, but I am very slow and a long way from rigging any part of it.
