>>2712399The tradeoff with ropes is the thicker it is, the easier it is to use (esp. climb) but the harder it is to transport. I use 5.9mm Sterling Powercord for my ultralight rappel setup, at that diameter you can't do better for strength and abrasion resistance. But I'd need some kind of ascender setup to climb it, probably a Petzl nano traction.
>body rapelWho are you, Tintin? Use an ATC or a figure 8, it will cost you $20 and work on any rope. For a harness, google 'swiss seat'

>full static or semi staticFor your plan, I don't think there's any possibility of shock-loading the rope, unless a security guard flings you out of a window with the rope tied around your ankle. So you want static.
Out of curiosity, how are you gonna get through the door?
