I wouldn't mind trying my luck on Dykh-Tau & Koshtan, but this year since a long, looong time I have a climbing partner again. We will be in the Russia from the 4th of july - 20th of july. We will climb Elbrus and maybe some other mountain - no real plans yet. I'm not too sure he's up for the other two, but I can always ask him. Still wouldn't fix the dates though... .
Ow and when you are in Russia, I'll probably attempt my luck on Mont Blanc.
