In reply to JStearn:
I did Kasbek in 2015 by the normal route which is a glacier crossing followed by some Scottish 1 snow. Info is hard to get but there were plenty of people in the area who helped. We used Georgia (Caucasus) 1:400,000 Adventure Map & Svaneti, Kazbek, laminated, GPS-compatible (its on Amazon).
The whole country feels very safe and friendly. We did a peak opposite Kazbek which was ridge at about scottish 2 I left my map there so I can't remember the name. It was a case of look at a line and go for it.
Good luck its an ace place. Loads of Poles, Iranians and Indians climbing there feels very different from the alps.
Just checked I think Kazbek is some way from Mestia, we did go there too but did not get anything done.
