Not too far back from the pitch head 5 m ish - squirm up the crabwalk sytle rift. then move forward - there are some P bolts up there. Just makes the pitch a bit more 'airy' and longer. Seem to remember it being a bit awkward to get up there.
Just before the pitch, as you face going towards the pitch, there is an alcove on your right with a hole drilled through the rock used as a belay. Clamber up there and then thrutch a bit upwards until you can make progress horizontaly. There are various 'p' hangers providing alternative hangs.
Its a little oxbow. just climb into the oxbox then climb up the rift until you hit the roof. you can also come in from nearer the entrance using the old "climb up, hit the roof and traverse along above the rift" trick
I have. But then I was told on one of the occasions it was removed due to extreme wear by the person who removed it as it was becoming dangerous, so I was prepared and brought one to use and left it in-situ. On the other occasions we were able to cope without the handline.
Somebody may say "Yes - it was there on Saturday", but it may have been removed on Sunday or today.
If you think you really need to have the handline there, its best to be prepared.
