Well, unanodized is unanodized. I would think that would just be the raw aluminum, I ordered mine unanodized. The stock cockers are anodized, its just black.
I would still stay with the unanodized model, and get a custom color from somewhere. I had my done with blue and clear lines, and I like it much better than standard black. For me, I wasn't going to spend that much money and not get something custom. I had P.K. do it and they are really too expensive now, I would try somewhere else. They do good work and I got it back in about 2 weeks, but I had to pay for it.
As you probably have already read, if you go with the black ano from AKA, its the hard industrial anodizing.
