Perhaps a professional climbers rope
Like MammutCrag Dry rope?
Dry-treated climbing rope ideal for rock, ice, and alpine climbing
9.5mm diameter is strong on sport climbs and light on multi-pitch
Dry treatment exceeds UIAA for repelling water, dirt, and abrasion.
I was thinking firefighter/rescue worker rope, but i think they use think straps.
I found this.

Not sure what you guys might think of those ropes?
The mammoth pro climbing is like 300$ for rope.
