I like the gunmetal CSL finish Andy. Did you get them done like that, i assume it's not a standard choice? I have CSLs and one is badly kerbed so my choice is either get new wheel, refurb both on one side (they can't guarantee colour match so i'd have to refurb a wheel that doesn't need it) or perhaps do them all in a darker gunmetal similar to yours.
If you got them done, who did them and do you recommend?
