550 parracord for climbing?

[Binnie]

a single piece of 550 paracord can support me, and i'm 100kg.

It's quite springy, so not that suitable for climbing, though i'd use it for climbing, just doubled up for safety.

I do have 30m of 11mm "static line" which i have used for abseiling,

the whole getup including traditional descender and harness only cost me around £90,

I use the line doubled (a loop round your anchor, and two open tails at ground level, twice the rope, twice the friction, half the effort, i can hold myself still with only a gentle grip of the line.

also very handy for recovering your line if you don't intend to climb back up.
