Quoted from DiabloRush:I'm very surprised no one else has provided their detailed comments. There's been almost no discussion from actual owners (either negative or positive). Those reviews will come, fairly quickly I would think.
I expect most reviews will be positive, whether people can tell any difference in performance or not, as those who spend the money naturally want to justify their purchase. It's just human nature. They look very nice, but I'm not a fan of metal rubbing against metal without a self-lubricating bushing.
