I use various test (sizes of fishing line) you can get from very fine to very large.I have a P-6E Hawk that came with steel wire in the kit for the rigging but I will use fishing line painted steel instead, much easier to work with.

so you think that using fishing line is easier than steel wire?
I was thinking on using some .008 guitar strings cut to size for my next rigged plane
