Druidh, I didn't favourite the threads but I think it was roadcyclinguk forum or something, they had a lot of "bike for a grand" threads and there was at least one person who had returned theirs. The issue seemed to be an irregular "bubbly" finish but it was affecting new frames, so if yours looks alright now you should be fine. TBH there were a lot of roadies doing down the entry level carbon frames, which I reckon is just snobbery. I'd be surprised if there was much difference between the different Cayos apart from paintwork and components.
Traildog you're right, the Stealth is TT, its the Pro Carbon I am after.
