This technique helps on low-angle and featured terrain or windy days. Though you should always tie stopper knots in your ropes, dropping them 100 or 200 feet can cause problems. To combat this, use “saddlebags”: Once the ropes are threaded, tie their bottom ends together in an overhand on a bight and clip this to your harness. Coil the ropes from the knot upward, creating a saddlebag by attaching a shoulder-length sling to a gear loop and hanging the coils through this. Pull out the coils as you rap.
the second’s set-up, useful if climber no. 2 is less experienced. Have both people set up their rappel at once, devices extended. The “top” climber (second to rap) sets up her device snug against the anchor. Meanwhile, the “bottom” climber (first to rap) sets up her rappel on the brake-hand strands just below the top climber. The weight of the first climber will lock the second in place. Once the first climber unweights the rope, the second can rap.
