Dom used mtx33's and as solid as they are, he found himself restricted to 35+ tyres. I used 23mm rim and could fit anything between 23 and 38 on that frame with same type of rims. Unless your going downhill on it, leave 29er rims alone.
By the way, the exact wheels in those pictures are still available, mack's with A23's. They're on a Samson atm, but would like some silver wheels for it.
Seeing those pictures hurts even more...
