Went through lots of tripods, didn't really care for the old style Gitzo collars on the legs, but when they came out with the new style locking collars in the 6x series, I saw one and I was sold. The 5-series are stable enough for ULF or long lenses with 35mm, but at the weight of what I would previously have called a "medium weight" tripod, so when I got my GT5540LS legset, I was able to sell off various other tripods, and I have a few different heads suited to different tasks or how much weight I want to carry. Mine came with a long column that I rarely use. I often use it with the medium column for tabletop stuff or the flat plate in the field.
For a compact tripod I've been using a little Linhof Report for several years, but I think my three-year-old sat on it while it was closed, and now the legs don't move so easily (fortunately it wasn't too expensive, despite the Linhof branding), and I'm debating whether to replace it with a Gitzo Traveller or the Feisol in that size at around half the price. I'm leaning toward the Feisol, because I think I can use it with a head that I already have and like, where I'd be paying for a head that I don't need or want with the Gitzo.
