Old Man: Climbed two routes, neither had loose rock but the rock is very sandy.
Rora head area: Climbed one route on Rora head and rock was good quality and varied between sandy and bullet hard.
Cliffs before you get to Rora head itself are a lot more variable. Climbed a few routes where the rock was a bit worrying but not a total choss fest and tried to put up a new route but gave up when everything was snappy as hell or lose blocks.
St Johns head: Reputation is appaulling but I've never climbed there.
Vomitting fulmars are a horrible problem on all the above areas. Only wear clothes and climbing shoes you wouldn't mind binning when you get home.
