Hi all, I have read through a lot the forum topics on tripods and there was some great info there but some of the posts where fairly old. I have read that the 501 fluid head has been redesigned and is better than it used to be, has anyone used the new version, and if so, is the 503 still a much better head? Also, has anyone used one of the monopods with the legs that open up on the bottom, would they hold a xh-a1? Thanks for the help!
