Nice one Richardg.
Yes, of course - Mick Phipps, aka "The Oracle".
That area is very much on the Orpheus' patch, so delving into OCC literature would bring rich rewards. If you really want to research it in detail it might be worth asking permission to arrange a visit to the Orpheus library and glance through various hut log books. These often reveal gems which didn't always make it into published literature. The excellent Orpheus Newsletters (less easily found in other club libraries) also have vast amounts of information of this sort in them.
