When I go shooting, Really Right Stuff tripods are what I count on. While I manage to shake loose a part or two every six months or so (the rubber screw-in feet for example), the tripod are rock solid and the service is outstanding.
My favorite tripod for all around use is the TVC-24L, that is, if I have to carry a tripod for miles, it is just right. I actually prefer shooting with the TVC-34L even more, but I don’t like the 'carry' aspect. The "L" versions are very important to working in steep terrain, since the extra leg length may be mandatory.
