In reply to A Longleat Boulderer:
Here's a solution that minimises fankles. In addition to the usual stuff you'll need an attachment lanyard each and a carrier bag with strong handles, Aldi or if you're feeling a bit special M&S. Either way they stuff into your pack pocket.
This is a slightly simplified version, it can be slicker but it's hard to convey in a page of text.
!!! It's absolutely imperative that climbers make sure they are attached to the anchor with a lanyard before untying from ropes !!! An old rope access adage: always add before you subtract! I have a story about that but luckily I'm still here to tell the tale.
- Climber A has led the pitch, Climber B is seconding on Red, Climber C on Blue.
- Climber A belays the dead rope into the plastic bag as they ascend.
- Climber B is going to lead next. The Red rope is already stacked the right way, so all good.
- Climber B needs the top end of the Blue rope which Climber C has.
- Climber C unties and passes their end of the Blue rope to Climber A.
- Climber C doesn't have a rope to second on now, so Climber A needs to untie from the Blue and give it to Climber C.
- Climber B is now tied in to the 'top' ends of both Blue and Red and Climbers A and C are tied to the 'bottom' ends of Red and Blue respectively.
This method means that the rope goes into a bag and doesn't have to be 'restacked' when swapping leads.
