Thanks for the input guys (been away for a few days).
As Dr NIck said most the top outs have new bolts placed by him (thanks i couldn't remember who it was who did it) and that covers most of the courtyard area now.
Think someone come through and did another batch because many of them now have 2 new stainless anchors.
I have fixed up a few more over the past 6 months and have headed down the hill to do some easier below 16 stuff and put up some mixed routes on stuff that didnt appear to have been climbed. Anyway i took the approach that mixed is best if any new stuff was to go up (this is areas away from the courtyard). As a result there is a few carrots down the hill on the lower cliffs (maybe 3 or 4) but the rest of it is pretty much as is.
Been surprised that its had an increase in traffic over the past few months which is seeing the courtyard climbs clean up nice and as a result you probably don't need your brush with you any more.
Get down there and have a climb if you haven't been there. Early mornings its in the shade until 11:30.
Thanks for the response again.
EDIT:
Actually would love to know who was the person who took the time to bolt the too harder roof climbs down near aid walls. Would be good to record them if possible. Any leads would be much appreciated.
