In reply to OwenM:
> (In reply to RockShock) Yes you use your spare rope, that's what the coils over your shoulder are for. Never used stopper knots, I would think that if you did use them you'd have to use another rope (could be the other end of your rope I guess).
Yeah, the problem is that if you decide to haul your partner out, you will be pulling the rope that links you and your partner, so the knots will get in the way anyways. It's not a big deal when using Tibloc's as it's relatively easy to remove it from the rope and move down the knot, but with prusiks it getss fiddly.
Other consideration is that if you are pulling the rope with knots, the knots will have to pass through the pulleys as you pull, so this adds another thing to watch for - the advantage of RescYou would be that rope linking you to your partner is external to the pulley system, so whatever you pull out doesn't mess later with the pulleys/crabs...
In general, knots on the rope are pain in the back when hauling, but I've been told that in two-man teams they greatly help to stop the fall - so I normally have few of them tied every few meters in the central part...
