I have a question about tripods. I am currently using a Vanguard. It is the middle of the road carbon three piece. I have been using a D800 with a 300mm 2.8 and plan to buy a 600 mm shortly. I want something super stable. I ordered a Gitzo GT3532LS. It was all good until I realized the maximum height is about five feet. I am 6'5". I need something a little taller. I would like to stick with Gitzo. Having a hard time finding an alternative. Any suggestions?
