Well, I'll answer my own question-maybe it will help someone else. From the hut at Triglav Lakes over Štapce, across both Tičarice (by the way-no markings on Velika Tičarica, but there could be, it's not that bad.), then across Zeljarice to Zasavska koča I managed to huff up in 4 hours. Due to fog that accompanied me the whole way, I skipped Kanjavec. The tour is not difficult, it could be even nicer if you could see something.
