In a non-Mavic vein, have you ever considered Ambrosio Excellence? After almost 10 years of building my own wheels, and always with Mavic, I finally used a pair of them - also laced to the Surly "new" fixed hubs - and have to say they are very nice. I especially like the cool gold counterweight at the valve hole and they have stayed true blue in the short time I've had them. About $10 cheaper than the Open Pros to boot, but the seam isn't welded. Just throwing it out as an alternative to the norm.
