IMHO, and as others have stated, the Trulli is one of the best ROOs ever produced. It is a wonderful combination of two great materials: carbon and ceramic. Likewise, the color combination is complex and engaging, yet understated and muted. I also much prefer the 42 mm case size and shape, as compared to the 44mm case -- it wears much smaller (and the 42mm already wears very big for its size). Lastly, the Trulli is limited to 500 pieces, whereas the carbon is an unlimited run.
I had AP make a custom black hornback strap with grey stitching that complements the watch wonderfully. You could also do red stitching -- that would be more striking, but I wanted to maintain the understated quality of the watch.
