Just my personal opinion, but when I bought the Campy carbon Record group for my Waterford, it came with a carbon seatpost. I used it for nearly a year, but the black carbon contrasting with the polished stainless of the Waterford frame just didn't look right to me. Also, the dire warning in the instructions threatening serious injury or death if I overtightened the binder bolt was a compete turnoff. The 220mm Carbon record post weighs 190g.

Long story short, I replaced it with a 330mm alloy Thomson Elite that weighs 230g, and I love it. My $.02.

Lots of riders are on carbon seatposts without killing or maiming themselves, but I decided to play it safe.
