In reply to team fat belly:
These are summer observations rather than winter...
Had two weeks in Slovenia this August, based out of Krjanska Gora. I found it quite different in character from the Italian Dolomites. Deep valleys, longer approaches - all in all tougher! (IMHO).
It feels much less developed than the Italian side, prices in the city were very cheap (the overall holiday less so).
There are a couple of VF that I'd go back to do, but the rock climbing around our area was disappointing, poor rock, hard grades (Oh the horror!) Osp, which was a couple of hours south looked much, much better.
Winter will likely be very different.
Have fun,
Steve
