I had them replace the black carbon fibre with the matte sidesand standard clear for the battery door.
They tried talking me into going with the silver/grey carbon fibre back and sides. Told them I didn't like how slippery the black CF was, he said the grey is different so I felt it and what do you know, it has that rubber feel to it. The black CF was very slipper and no rubbery feel, when I originally had it done I was deciding between the black and grey but decided to try the black. Wish I had chosen the grey, it may have looked better and def feel bettery.
Oh well, for now I am on clear for the battery door and matte for the sides, I think it looks good. Only probem is I think the side will get messed up and start coming off after a short while, they are hard to stay on unline the screen and battery door.
