I agree with Jorge.

I just got back from the mountains with my brand new Wehman 8x10 and my trusty old CF Gitzo/Arca Swiss Ballhead/RRS QR mounting plate combo. In the wind - solid as a rock, as always. Can't say the same for my Calumet focusing cloth, however.

I never had a problem with my 5x7 Deardorff on the CF Gitzo either. In addition I've clung to the side of mountains with a much heavier camera on the Gitzo (a 16mm Bolex Rex V with Norris Animation Motor) - no problems there, either. The vibration damping properties of CF are excellent, by the way - very close to wood.
