I have the Gitzo GT1551T travel tripod. Very small and light. It came with a Gitzo head, which is pretty much what you say you want. I used it on one trip and took it off and left I somewhere I can´t remember. I currently use the RRS BH-30 ball head. I have attached an image to show that the tripod collapses almost totally and one to show size next to a 1DX, with the 200-400 f4L attached.
I am very happy with this combo up to the 70-200 f2.8L IS II lens.
