Hope has a good reputation for lots of high end mountain bike stuff (King and Wood are a little more common over on this side of the pond). The only concern that I would have about the Hope hubs is the aluminum freehub body. While I wouldn't worry too much about titanium, aluminum is a bit more delicate.

There's a video out there on servicing the hub that details how to remove and replace the bearings. It doesn't look difficult but is more involved than the Phil Wood hub service. My rear hub practically falls apart when I remove the end caps.
