I don't think Gitzo legs were ever 8X, I had an old series 3 CF with a big cross-section but it was just heavy and unwieldy. Large cross-sections need not have a direct correlation with CF layers, and as Lars pointed out- older CF tripods just were not as good as current generation CF.
Sorry, I just can't find the reference, as the older Gitzo sites are gone, and 6x is no longer news. I seem to recall their older tubing was 8 layers and 1.5mm wall thickness, while the new is 6 layers and only 1mm thick. No matter, though, as the new are definitely better. I still have my old G1228 MkII, and it's noticeably heavier than my GT2540, which is two generations newer, but otherwise the same size.
RRS has also quoted that their CF tubing is also only 1mm wall thickness. Anyone measured one of the Chinese-made clones? Just curious.
