How to walk from Oberurnen to Niederurnen in more than 10 hours

Oberurnen – Tschingel – Gugger – Hinter Sunnenalp - Fridlispitz - Hinter Sunnenalp – Lochegg (P. 1535) – Ober Lochegg – Wänifurggel (P. 1610) – Mettmen (P. 11811) – Planggböden – Planggenstock – Hirzli – Schwinfärch – Ferienheim – Eggrüti – Stogg – Gfell – Schlössli – Niederurnen – Ziegelbrücke

Remarks:
Snow above 1400m, knee-deep at Lochegg and from Wänifurggel down to Mettmen.
Under these conditions I would rate this hike as T4 (slippery!)
The weather was much better than forecasted!
