Carbon fiber 'pods are pretty light. For years, I had a 13.5 pound Bogen 3051, and a somewhat lighter 3040; two years ago I bought a Flashpoint 1127 carbon fiber 'pod from
Adorama, at about the time they were closing them out. I suspect it's made by one of the bigger Chinese CF 'pod makers, and re-branded, but currently,
Adorama says the 1127 is discontinued, and all they have in Flashpoint are much more-expensive models.
The 1127 was my first-ever carbon fiber tripod, and I was AMAZED at the difference between a 13.5 pound tripod, with a ~2.5 pound, full-sixed Gitzo ball head, and a roughly 4-pound CF tripod...WOW--the CF model is actually carryable on all-day hikes and stuff. I use a sling made of an old camera strap, but wow, CF is just sooooooooo light in weight. So, if you want a carryable tripod that will not exhaust you, definitely go CF. Compared to even the light-ish Manfrotto 190 legs Majeed has, the Flashpoint CF legs are lighter, and around the same length when collapsed.
I went with the 1127 for price, wight, and three-section legs: I do not love or even like the twist-lock leg design, so three-section was PLENTY of leg-locks for me to mess with locking and un-locking.I, personally, would not stand for 4-section legs.
