Oh wow I can't wait to see the final build! I have always lusted for a Moots. One day...

I used the Blunt SL 29er rims for my commuter- the wideness of the rim really widens the tires footprint and makes the sidewalls feel more stable, without the weight penalty of a wider, thicker tire. They make my 35mm commuter tires look like 40s. My next MTB wheelset (if I ever need another) will be built with those, good choice.

I bet you are counting the hours till you can get some time on the trail with that beautiful bike!
