In the past for the wheel, we've had the spokes in the center of the wheel, which makes it a two op process: machine out one side, flip, and machine out the other. For this wheel, one side gets machined out, and it's done.
(as far as the two op wheel,
here 's an example.)
[edit] I'm realzing now that people are talking about the spokes not coming to exact center on the wheel axel. So as for that reason, I've seen many wheels that don't (vex...), and they've held up quite well. So as far as that's concerned, it's all style. [/edit]
