Which do you prefer, Pan-Head or Ball-Head, and why ?
I have the SLIK Pro 700DX w/700DX Pan-Head
It seems plenty stout and stable enough for my use.
I have never used the video abilities on any of our cameras; only still shots.
With the 50-500-lbs Sigma at 500mm, it does seem to take me forever to zero in on an eyeball-sized target at fifty feet; I get the focus point exactly where I want it, tighten the handle, and it has moved a hair's breadth, either to the left or downward.
If I anticipate this and zero in a bit high and to the right, then it will be dead-on once I tighten the handles.
