bbugari1, thanks for the nice description of this route across Black Lake - Osankarica - battalion - 3 nails - Silent Lake - Klopni vrh - Pesek.
I also don't stick strictly to SPP, because it bypasses some interesting points. Usually I go from Poštela or the lower cable car station to Belvij, past the viewpoint and military radar to Areh (bypassing Mb. hut). From there to Žigartov vrh and down to Bajgot.
This year I went across Pohorje for the third time, well from Bajgot to Rogla but on another route namely by road past Lahova žaga to Silent Lake (bypassed Klopni vrh and hut), from there across Kladje past Kurji hrib and across Brvni vrh to the Zgornja brv junction. From there not to SPP and straight to Pesek, but I went by road to the foot of the Jurgovo ski slope and up it steeply to the viewpoint at Rogla. "Pleasantly" steep is that Jurgovo, especially with a full backpack on shoulders
Followed by a walk around Rogla to the construction site of the new wooden tower of the Crown Path. Then back to the viewpoint and from there through the forest to Pesek.
Day 2: Back to Rogla to the tower - Lovrenška lakes - Ribniško lake/peak/hut - Črni vrh - Kope - Partizanski dom.
During the ascent from Šiklarica to Ribniški/Jezerski vrh I recommend viewing the wreckage of the crashed plane in which a father and son from Austria died.
Day 3: Classic descent Partizanski dom - Kaštivnik - Kremžarca - SG.
To everyone crossing Pohorje for the first time I recommend a 3-day tour nicely "easy" with "chilling" by lakes, at peaks, huts etc
For a 2-day tour from Mb I recommend overnight at Pesek or, for a bit faster, at Ribniška hut.
