In reply to TobyA: Thanks - having examined things further via westmidlandsrock ( didn't know there was a guide until now!). the potential crag is in 'North Quarry' - and it is suggested summer lines have been done ( but rock loose); the one route is in the quarry east of reservoir wall - cant find a name for it; and other route is in 'summer hill quarry' which again doesn't seem to be in guide book/topo or on crags list.
so maybe new routes!! - but I am sure there are others as insane as I who have slogged up vegetated frozen mixed ground for a little sport!
thanks for the info - a few real routes to try next time they rime up.
