Poly Fibre Rib Lacing vs. Fishing Line

[Rolly LSA]

What is the difference between Poly Fiber Rib Lacing (Stitching) and poly fishing line??

I suppose it depends on the fishing line, but the stuff I used for rib stitching was not like anything I've fished with. Do you need some? I'd be glad to send you my roll if you promise to send back the remnant when you are done. I have more than I'll ever use, but would like to have a little around in case I need it later.

One is a spun lacing thread / string which is impregnated with fungi-killing wax and tested / approved for use on aircraft. It looks like cotton.

The other is a nylon mono-filament which isn't tested / approved, and is used for fishing... It looks like a bad idea?

Now I know. It does sound like a bad idea. Thanks for the reply.
