Thanks for the recommendations, all. I'm leaning toward the Feisol. Looking at the specs, it seems to be in the "sweet spot" for cost vs. functionality:
Gitzo GT1550T ($675)
Leg Sections: 5
Weight: 2.2 lbs
Closed Length: 14.2 in
Load Capacity: 4.4 lbs
Feisol CT-3441B ($399 - includes ball head)
Leg Sections: 4
Weight: 2.4 lb
Closed Length: 16.9 in.
Load Capacity: 13.2 lbs.
Bogen 055 MF4 ($360)
Leg Sections: 4
Weight: 4.4 lbs.
Closed Length: 21.3 in.
Load Capacity: 15.4 lbs.
It also comes with a ballhead, sparing me the hassle of picking one that fits. (Some have complained that you can't fold up the Gitzo with the ballhead attached.)
Still, I'm wondering if I'll regret not going for the flyweight Gitzo. It's actually heavier than the Feisol (when you add in a ballhead), but seems a lot more compact. Not just shorter, but less bulky all around. (Of course, that means its max load is lower.)
