I'd think twice about DuraAce hubs for these wheels unless you can get the 9-speed version. The 10-speed version (last I checked) has an aluminum freehub and takes only DuraAce cassettes (expensive and hard to find). I've got the 9-speed version (from 2006?) with Ti freehub for one of my wheelsets, and that is compatible with all standard Shimano cassettes including 10-speeds. DuraAce hubs aren't recommended for consistent use on a loaded touring bike - they are light enough to lose durability.
