Hi, currently looking at upgrading my tripod and tripod head. I am looking at buying a gitzo tripod (GT3543xls) and the gitzo gimbal. Do I need the leveling base and adaptor ring for it? I am sort of thinking that if I am in a bird hide already, I have the time to get the tripod level and set myself up properly. I am only shooting still photos at the moment. Maybe if I was looking at getting in to videos I could see the use of a leveling base + fluid head. Anyone had any experience using this set up with or without the leveling base or has any thoughts/suggestions?
