I don't know about you, but I always don't have enough space in my suitcase.hard to see an improvement over the Gitzo Traveler one I have; much less RRS
I like Arca-Swiss mounts (and have 4 tripod heads with that) and a circular profile tube is stiffer/stronger than any other design
So, what's so great? It has some different 'things' about it, but where is any real improvement? Only packed dia. but is that such a problem ??
