FWIW. It is MY (direct) impression that the C40 was tuned to ride like a steel frame ....
Based solely on what I have read regarding stiffer-this-and-stiffer-that, it is my impression that in the past dozen+ years that most carbon fiber Road frames are now tuned to ride more like an aluminum framed bike ...
As simplistic as THAT may be, if it is correct then will that stiffer frame be better for you & beneficial to your race results?
If it is correct then I think the non-sponsored rider should suffer the 1+ lb. penalty & opt for an aluminum framed bike (I'm not convinced that EITHER the press fit BBs are truly beneficial OR the over-sized steerer is a requisite for a Road bike ... BUT, if you think that they may be then factor them into your decision) ...
If you have money-to-burn and/or you want to make a fashion statement, then you may want to consider an aluminum frame + (this is the fashion part) EPS drivetrain, first ...
If your race results benefit, then opt for that new (Colnago!?!) CF frameset.
