I do a lot of long exposures, a sturdy tripod is essential. It will not move a muscle!
I like the central column that can pass horizontally, it allows me to place the reflex much closer to the ground. I coupled with Manfrotto 496RC2 ball, much more convenient to use a 3D head, especially with the horizontal column.
The whole exudes quality is solid, it's heavy, there are no games in rooms. Foam grips on the feet are a great idea when it's 10 ° C!
So yes, there is great when it is folded, yes, it is heavy, but for me it is inevitable for a good tripod. I prefer having to carry a heavy tripod that will serve me rather than a seamless lightweight tripod that hurts his work.
