All I'm saying is that if you're gonna pump money into a wheel, start with the rim. Not sure if there's much difference in two wheels made using the same rim, but (for example) a Dura Ace vs Ultegra (or Super Record vs Chorus) hub. And the Royce is heavier than the Shimano.

If you really like the hub, go for it. But you may be spending the extra 200 euro on something that doesn't have much riding benefit.

BTW, just looked at Chris King prices. You're right! They're even worse!
