I'm hunting for the right tripod to haul with an 8x10, looking at Gitzo CF, and noticing a rather complicated array of design options. I'd like to go with the new 6x stuff, but I'm not sure which one would be comparable to a 1325/1327. I also would like to know more about these "all weather feet" I've seen on B&H or whether one can get spikes for these tripods. I plan to get an Arca B2 ballhead. Does anyone think there may be a better one?
