Thanks for starting this thread, I'll be watching to see how the ceramics work out for you if you go that route (I'm thinking of going ceramic myself, but mostly for extra longevity). I just bought the same bike a few weeks ago and noticed the rubbing right out of the box, so I had to reset them which helped. I still get intermittent rubbing in the front; when I do I give the brakes a good press and that usually makes them quiet again.
