I'm looking to go semi-stealth, and getting some things together for my DIY projects. Is there a (one stop shop) where I can get Black Shock Cord and Black Guy lines with the reflective trace in them?

I want them to be for the most part stealth (trying to avoid yellow, orange, red lines), but still be able to see my lines with my headlamp so I don't closeline myself at night.

I've found some options on eBay, but it says Bungee cord, which I think is slightly different. I even found some Paracord with reflective tracers, but kind of expensive.
