Actually,

I think the F18 class disallows high strength lines to be used as trapeze lines. I'm not sure whether the Viper uses lines here or wire. I seem to remember the Blades and Falcons coming standard with high strength line trap lines.

Personally, I will never use wire in this role again. Lines are cheaper, lighter (by 0.5 kg) and damage the sails and mast much less then steel trap wires.

With a needle and polyester thread or splicing one can make ones own timble eyes.

It all adds up.
