Induro BHL2 + Gitso GT2531
I've been extremely impressed by Induro and their BHL ballhead line and by Induro period.
Personally I'd give the Induro CT213 a look at as an alternative to the Gitzo. Or for about the same price or less than the Gitzo, you could get the larger more stable, and heavier, Induro CT313.
Even though Gitzo is a top preforming and expensive tripod, their customer service, warranty handling, and parts department have been getting a very bad reputation lately.
