In reply to antony638:
Both good hubs, I wouldn't let a few bad Generator reviews put you off. Could you comment on what the reviews said was wrong with them?
I've been running a 150x12mm rear Generator wheel on my DH bike for about a year now and have very little to say about it, it just does the job. The only thing I've had to do is change the outermost bearing on the drive side, but I ride year round and I don't think this is unreasonable. Hub comes apart for servicing easily. Not as noisy as the Hope, but wether you like the noise or not is personal preference.
