Ascent of Willy Merkl Gedenkweg as Tick or First ascent

Funny little aid nonsense with a rope pendulum in the middle. Freed the start up to the pendulum (easy) and the section from the threaded shoelace up to the last bolt, I would say that amounts to 8- or so with some powerful moves into the crack, then a nice hand crack with good jams. Getting over the last bolt is probably at least 9-, no footholds at all in the right wall and no more jams. So all in all something like 7/A0 or 6/A1. Astonishingly overhanging and you definitely need cams even to aid it. There used to be two additional pegs somewhere that are now gone, according to the Buchner guide.
