Build kit is one thing, frame level another. Regardless of components, the C'dale EVO comes in three carbon layup/quality versions:
Regular EVO.
EVO Hi-Mod. A little lighter, more money.
EVO Nano. Stupid light, stupid expensive (only on Black Inc. model)
I would get the Hi-Mod, personally. Currently riding a 2011 basic SuperSix, non-EVO, no Hi-Mod, and it's a very nice bike. One of the fastest, most comfy frames I've ever owned. With the EVO being heralded as superior I can only imagine how nice that thing is. Unfortunately, with the looming, and IMO somewhat inane, industry switch to disc brakes, I can't justify throwing that amount of money at the current technology.
