I am looking at Gitzo carbon fiber tripods - GT2531, GT2541 and the GT2541EX. These are just the tripod legs, no head. Can anybody explain to me why the maximum height of the carbon fiber tripods are around 5 feet? I believe this max height is with the column fully extended. I am a tall person at 6 feet 3 inches. Will using these tripods give me pain in the back from arching over to use the tripod? I would like to take these tripods hiking. The only tripod I seen that has a height over 6 feet is the Slik product but they are not carbon fiber.
