Why is weight a concern if you are not packing it?
I prefer tripods that get the height I need with leg length alone, not center column. Cameras and optics are more stable the closer they are to the apex of the tripod. Center columns add instability. Any instability adds vibration. Vibration causes blur. Blur causes eye strain. Even with the best optics on the planet.
My newest tripod I just bought is a Really Right Stuff TVC-34L MK2. It extends to 68.4" and weighs 4.55lbs. I am 6'7" and with the tripod head it is tall enough for me to stand behind and glass. I mainly bought it so I could shoot my rifle off it. I bought it gently used off eBay for a steal but it was still "expensive" to most people. I hardly ever pay retail for equipment. I search craigslist/eBay/forums for high end gently used equipment that I want. The deals are out there you just have to find them.
RRS, Pro Media Gear, Gitzo, manfrotto, induro, benro, all make quality tripods but they are not inexpensive.
