Hello Alek,

Last year Jorg Verhoeven (world cup winner) climbed the route to the summit. He says after pitch 22 there has been rockfall wich partly destroyed the route. Most people descent after pitch 20. He continued with only a small rack and it took them a long time to climb it. And the descent over the south face is not an easy task.

Here's the link of their (short) trip report. Maybe google translator will help you understand some of it.
