Yeah, that's one of the options. Those are what's sewn into my REI Half Dome I believe. Problem is that you'd have to sew those in somehow or figure out some other way to attach them.
2mm or 3mm dyneema with clam cleats(line lok) no stretch and won't absorb water don't have to get specific camping type lots of sailing shops sell it by the mtr, I have also bought some from ali express and has not failed me
In the past I've used Glo line, but lately I've just been using 2mm IronTwine.
Much cheaper and stronger.
I've been using it for all my diy 5-string projects, guy lines, and kill kit cordage.
Only downside... not reflective. Oh well.
