Tina White approaching a typical rebelay from below in Kaninchenhöhle. Note that there is too little slack in the rope above the rebelay, though there is no doubt that a lot will appear once the rope is loaded.
This is something to watch out for on the descent: when the slack disappears as the upper rope is unloaded, it is possible to find that you can't remove your descender from the rope without attaching an ascender to re-load it.
This is an mild example of an unnecesarily acrobatic rig which should be re-done on any route with heavy traffic.
