What's the good word on centerlock rotors? Do people hate them? Are they totally rad? Obviously shimano is the only group still doing them. I'm looking at building up a new wheelset and the saint hub is dandy...but I already have a hadley front hub. I could probably pick up a saint hub for the same as I could sell the hadley front, and they weigh almost equal. I already have decent 8" rotors, but I don't know the benefits to centerlock.
