Climbed Rubihorm from Oberstdorf in less than perfect weather. However, it remained dry until long after I had descended again. Foggy enough to keep me from climbing Gaisalphorn, however.
I remember climbing this mountain many times many years ago (>15 years) from both the Oberstdorf and Reichenbach routes. I remember the Oberstdorf route as quite streneous with lots of zig-zagging to the ridge.
