According to this: http://www.bikeforums.net/showthread.php?376145-which-cone-wrenches-for-ultegra-hubs&highlight=wh-6600+locknut
you need two 15mm cone wrenches. But I have no direct experience with them.

I know this is old, but I had this same issue, and eventually figured it out...
The locknut uses an allen wrench. There are no flats on the locknut. The cone uses a 20mm cone wrench.
