I have a RRS panning clamp but rarely use it because I find I level the base, then tilt the camera up or down with the ball head (on a cliff looking down or in a valley looking up) Then pan from the base of the ball head not at the clamp.
So my options are a RRS BH55 on a RRS TVC-33 tripod with a RRS leveling base or a Burzynski head on a 100mm video bowl on a Gitzo 5531s tripod. Just not sure how well the Burzynski pans? I'm familiar with the RRS equipment but have never seen the Burzynski so your advice is needed to make the correct decision. I already have a gitzo leveling tripod for hiking I'm looking for maximum stability on this one
