I've been reading postings and reviews, and agonizing for many months on a tripod / head setup. Got it narrowed down now but I need you folks to push me over the edge! And maybe someone else can benefit too. Many, many thanks to all of those who have posed similar questions before and those who have taken the time to craft well thought out and knowledgable answers.
I need something I can take hiking without thinking too much about the extra weight it will add. I don't have a long gear list but want something that will hold up with future gear, too - For example, I hope to add a 70-200 some time. But no 300mm on the horizon.
TRIPOD: This part is pretty much settled. I've decided to make the deep investment (for me anyway) in Gitzo. Considered the Chinese stuff, looked at Manfrotto and many others and decided on the weight/stability/quality factors of the new Gitzos. I'd probably be fine with many of the others I've seen recommended too but I think I'll go with the Gitzo 2540. Considered the 1540 also, but with this being my only tripod I think the additional stability is worth lugging the extra 1/2 pound when I hike. Comments welcome.
HEAD: Not as certain - here's where I need the bigger push. Got it narrowed down (at least at the time of this writing!) to the Markins Q3, RSS BH-40 and Archatech V2. Only thing I can add is I'd like to do some panoramic work.
So, who wants to push? 
And if you are limiting yourself to only one tripod, then I think you might want some room for a little growth. If you expect that not to be the case, then John's recommendation to go 1540 and 3540 is a good one, albeit more expensive.
