For what it's worth I think I may well go with ITM, especially as I was supplied with an ITM/Colnago stem.
I have some Deda carbon items I was thinking of using but I just don't think they will look appropriate on this frame. I'll save them for something else.
For the groupset I have Record alloy chainset, Chorus alloy brakes and front mech, Record carbon shifters and Chorus carbon rear mech.
Saddle is a Selle Italia Flite gel flow.
Any further comments or advice entirely welcome, and thanks for all the posts so far.
