I have left a copy of the guide at the bar La Ruota in Urzulei (turn R on way to Baunei from Cala Gonone/Dorgali just after cheese factory), and here's a vid of one of the new problems. I tried this last year, couldn't get anywhere, but after Travis did it was much more determined to keep trying. It really does show what morpho means...
I reckon that from mid-Sept to mid-June you can boulder fine at Serra Oseli, looking for sun/shade according to season. Today it's 22°C on the coast, up there it was nice to doze in the sun between goes but not greasy.
