I have seen many pictures of Basalt Black TT's, but not of the standard non-metallic black paint. I tend to prefer standard black because it doesn't look grayish under some conditions (and when clean, looks really well... black). Would anyone advise against this choice ? The usual reasons given for choosing basalt is that it hides scratches and dirt better, but doesn't the normal black look more spectacular when clean? One more issue would be the durability of the paint. Which has a "thicker", more resistant clear coat if any?

Additionally, for the folks that went to Spain, from first hand experience, which color did you prefer on the TT black or speed yellow?
