Spending my spare time building my dream bike in my head while I wait for the frame to arrive, I am completely confused and uneducated as to which componentry I should choose.

I have a vague idea of what I want, but I don't know how to get there.

Ideally, I would like all of the weightlessness, range, and ergonomics of the new carbon record groups, but with the the beauty and simple esthetics of the old alloy groups.

I wish they would reintroduce a retro inspired group. Pipe dream.

Are there any good threads that come to mind comparing the differences/nuances between levels and mixes of campy builds?

I have no knowledge of which parts can be mixed successfully and which won't go together.

Ideally, I would just pick a new 11 speed groupset to base the build on, but they seem to be very proud of those. Even the ones that looked like they've been drug across the pavement a few times command decent prices.

So if I stay within campy 10 speed groups, say mid eighties til present time, is there a reference source I can use to know that the pieces I gather will work?

Any help greatly appreciated.
