I'll set myself a reminder to take some pics tonight. I ran it several hundred miles that way in the late summer, but switched back over to my knobbier/ mud tires for the winter. None of my pics are close enough to show the clearance, but I didn't have any issues with them.
I'm about 5'-10.5" and ride a size ML. There is definitely a tall head tube, so I run a 7° stem(I think) and no spacers. I find this puts my drop position about mid point between the drop and brake hood position on my road bike (ML Lynskey). I've been real happy with this position (with a wider Salsa Cowbell) on the forest service roads around here.
I put the other wheels back on tonight and took a few pics. I had no issues with them and never any rubbing, but I rode them during the pretty dry season around here. They clear, but not a lot of clearance if you start to accumulate mud on the sides. I run 33's during the muddier times around here, and have never had issues with them clogging.
I've never looked that close at DK200 (sorry, I just have a hard time with the concept of Kansas as a destination , cue string of angry posts extolling Kansas) so I'm not sure what the traction conditions were like but personally around here, if it is muddy enough to worry about mud packing in and building up, at least around here and with my riding abilities, I prefer a tire with a more aggressive tread than the MSO. In those conditions I've been running a 33 width Vredestein Black Panther. I'm still new to this and learning though, so maybe I'm totally off base on this.
