I'm trying to figure out what sort of ropes to take on a particular long route.
So far, the best notion we've got is to use a single (~10mm) dry rope, with something like a 6mm rap line to allow us 60m abseils.
This system is lighter than using half ropes, and the thicker lead rope means less chance of the wind carrying and knotting our rope (a real concern for this route).
What I don't really understand is how you rap with such a thin line (ie, through belay device), and what happens when both your rap ropes are such different sizes.
Any wise insights? |
