no one really 'owns' or 'looks after' said routes - and loose petzl-type bolts can *usually* be tightened back to security with a suitable spanner.
Today we were there with people who helped develop the place (though not those specific routes)!
Give Dave Musgrove (snr) an email and I'm sure he could organise something with respect to the lower-off on 'Rambling on my Mind'.
Later,
