I have a carbon fiber tripod, and I have an 8x10 Deardorff, but I would never use them together. Unless you know of a brand which is much sturdier than my Gitzo, I would stick with steel or wood. The inertial moment of my Gitzo is such that it would vibrate with a large camera mounted. It is not the problem of holding the camera, it's the problem of holding the camera still. Perhaps there is some massive CF tripod out there with inertial characteristics of wood or steel, but I haven't seen one in my travels.
