Personally, I don't see an issue with a little chrome diamond plate. Just because you wheel a vehicle doesn't mean you can't try and make it look nice too after recovery operations? My wife's JK has black diamond plate ranch hand steel front bumper, my truck has black diamond plate tool box and bed rail caps, and my interior YJ Doors are diamond plate. Its a matter of owner's choice and if anyone else doesn't like it, then don't do it to your own vehicle.
