That is why CULT bearings are so expensive (even though maybe unreasonably so). Not only do they have the ceramic bearings, but the cups and cones have the Chronitec treatment as well.
But will you notice the difference riding? Not likely. I like them because they seem impervious to water.
But I'm kind of agreeing with a previous poster who asked just how long you're going to agonizing over this decision @TonyM. You've started quite a few threads it seems asking essentially the same thing... The decision is yours. Best way to learn is to bite the bullet one way or another and experience things for yourself.
