thanks peter those are good points. i have gone back and forth trying to choose between the two. not having done it, it is not real clear to me how much difference there would be to me in attaching/reattaching the ballhead to the gitzo vs folding and unfolding the legs on the feisol, plus telescoping/untelescoping the gitzo legs is supposedly faster than on the feisol.
that is a good point about the diameter of the p0. i had not caught that. actually that would narrow the weight difference, i.e. i could go with the 10 oz p0 on the gitzo vs a 16-20 oz head on the feisol.
