Decluster your anchor: Put lap coils on a sling
This tip is from AMGA Certified Rock Guide Cody Bradford. While sadly Cody is no longer with us, his Instagram continues to stay up and is a great source of tips like this, check it out.
On a multi pitch climb, rope management is a key skill to staying cluster free and moving efficiently. The basic question is, ledge, or no ledge?
If you have any sort of a ledge, you can often (neatly) pile the rope at your feet.
If you're at a small stance or full hanging belay, the typical approach is to make lap coils over your tie in connection.
However, these lap coils can be cumbersome, especially when belaying a leader.
Below is the standard approach of the rope draped over your tie in connection. Do you think this might be awkward when you try to belay your leader from your belay loop? (Answer, yes.)
Solution: hang the coils from a sling on the anchor. The rope stays tidy AND out of your way. Much easier to belay your leader on the next pitch.
Here's a short video by Cody Bradford that demonstrates this simple and effective technique. (He's doing it on ice, but it works fine for rock climbing as well.)
