I have narrowed down my tripod and ball head choice to the Gitzo GT2530 legs and Arca Swiss Z1 ballhead. But before I make the purchase I'd like to see who else out there has this combination and whether they like it. Also, can someone with this combination tell me if the Arca Swiss ballhead is either equal to or narrower than the head of the Gitzo tripod. If the ballhead hangs over the head, I may need to move up to the Gitzo 3530 legs. I guess i'm concerned about the "fit and balance" being correct between these two expensive components. Thanks for any input.
