When tighening any carbon bits be sure to have the proper tools and torque ratings from the manufacturer.
Good luck - waiting to hear your assembly experience.

Regarding Campy - I think the above posters comments are valid. Try them all (SRAM too) yourself, as it is a matter of fit and preference. I've been Campy for many years - the one distinction used to be that Campy would handle multiple RD cog jumps with a single motion. Shimano required several swings of the right hand. I'm not sure if that is still true. Shimano electric sounds very interesting tho. Campy's 11 sp is not of interest to me yet, 9 & 10 serve me well. But I often fide a friction 6 cog that also pleases. If riding I'm happy.
