I have an 11 page description for the Tanne Du Bel Espoire to Grott De La Diau traverse (in English!), including 3 A4 surveys/drawings which can be posted to you if you want.
You mentioned in your text this morning about going off to France soon. I also have a rigging diagram and a bit of a map on how to find the hole for said cave - which I found very useful when we did it in '99', if you are interested.
Simon.
