Reputable, long-established brands such as Manfrotto, Slik and Gitzo, among others, will have invested a lot of time, research, engineering and money into developing carbon fibre products that will easily shape up to the worst conditions of expected use, but in terms of what you put on them is one of prudent decision-making. With CF being light in weight you don't want to put any camera on top that exceeds the published weight limit (I plonk either 400gm pinhole camera or a 2.3kg SLR on either, but the smaller tripod is never used with the big camera with legs fully splayed). You've probably already noticed by now the huge price difference between CF tripods and aluminium. Apples and oranges. My slender Gitzo tripod doubled its usefulness recently as a handy second walking staff during a slippery descent!
