In reply to davidbeynon:
This is eastern Julian Alps, aka the very definition of choss.
Lower part right after the Dibona ledge is IMO worse, higher up the rock gets a bit more compact, with some chossy sections. Also, if you run into very loose terrain you are probably off the route anyway. Note that definition of 'very loose' is also very loose and subjective
Bring a hammer and pitons (soft steel knifeblades, small angles) and know how to place them.
Also the wall is huge and route finding can be tricky at times. Start early!
I'm not sure about the required membership, but the overnight fee was 5£ a few years ago. Anyway, any alpine association membership card (BMC, OeAV, DAV, PZS) should be good enough to get the key, but I doubt the key lady will even ask.
Hope this helps.
