Before you do buy, take a look at the older Getzo 'Giant' Performance legs in aluminum. rises to eight feet, legs are adjustable in spread, and built like a tank, while giving great performance.
I've used one of these and it is very like the mountain that came the man, solid, unshakable and the closest thing to set in stone you might wish for.
The first time I saw this model in action, was during a long, cold night of shooting that included several architectural exteriors, at full height, with a 4"x5" studio camera.
There was a stiff wind and it never moved once, even with that 'sail' of a camera on top.
In a truck bed, on top a station wagon or SUV platform, ie. plywood sheet, or just a good ladder, those birds eye view points you can no see, now, suddenly become accessible, and that is it's great advantage.
This is the model legs I will add to my select tripods, when able and, seriously, if you're no hiking, will give you the best service for the dollar, it's just that good.
IMO.
