I took part from Kokava to Jelsava and it´s really good road with lot of twisty corners and good surface.
Went through this week (27.5.2014) and where the asphalt was bad, there is almost new surface.
I did part of this route in May 2013 & encountered really poor road surfaces most were like gravel tracks. This may have been left over from the poor winter so I would plan this route in high summer to avoid the gravel.
Gypsy villages can be a little intimidating with locals lining the roads to see bikes pass through villages.
I´ll give a four and a half star rate becouse of some small sections and it´s poor surface. But otherwise it´s a great road on twisty roads through beautiful nature, little gypsy villages etc.
