For all seeking info, let me add my experience;
1st day - Start in SG, along marked hiking path over Kremžarica, across Kop to Ribniška koča, where I overnighted. Walked slowly with breaks approx. 7 hours.
2nd day - past Lovrenška jezera, over Pesek to Klopni vrh, got a bit lost 2x, on path 6 hours.
3rd day, past Šumik, Areh, Bolfenka to Snežni stadion, walked approx. 8 hours.
Highlights for "non-hikers" to help planning and not getting lost:
- times on signposts are only approximate and net walking times (without breaks);
- red lines on trees are not some new - or maybe Austrian - markings, but are forest boundary marks - don't follow them - look for circles!!

- offer at huts is very good, everywhere they offer something hot to eat, recommend fruit, nuts, chocolate bars, sandwich for reserve in backpack
- At Ribniška koča and Klopni vrh where I overnighted, no need for your own bedding - elsewhere - don't know.
The path is gorgeous, varied, quite solitary at this time.

Just gotta get going!!
