In reply to pec:
Thanks all. I'm heading out there today but I've got 3 weeks and won't be heading to Sorapiss and the Slataper until the last week but hopefully there'll still be snow to melt for drinking water. On the other hand, the snow might put Tofana (hence the Dibona question) out of bounds.
Any more useful info re my questions still welcome, I'll keep checking this thread (assuming we can get a connection on our crap "smart"phone.
