Spectra and kevlar are both considerably stronger than steel of same
diameter, and a lot more flexible. The downsides are that they crush
more on the spool, don't stack or lay well and they do not resist
abrasion well at all.

That's why I suggested rock-climbing rope, specifically Static Line
which doesn't stretch or twist under load like the usual hardware-
store Nylon rope.
