Message: <blockquote data-quote="Alexis Powell" data-source="post: 3468556" data-attributes="member: 5327">I went from Bogen 3126 (similar to your 3130,  but w/o quick release) to the 700RC2. In my experience, the latter is not nearly as smooth or adjustable in tension, and is highly variable unit to unit. One thing that I don't like about the 700RC2 (based on experience with several) is that when the tension is adjusted low (Note: some units never become truly low tension, limited by the viscous grease in the design. In my experience these heads do not become smoother at all in use), the head becomes wobbly. Both of those heads are limited in the ease with which one can balance a scope that is nose or tail heavy because they both take drop-in plates. But the 700RC2 sure saves a lot of weight, so I used it with my light rig for a long time. I'm much happier with the Gitzo 1720, which is lighter, more adjustable, doesn't get wobbly at low tension, can take different length plates to balance different scopes, can be adapted to the Arca-Swiss QR plate standard, and is easier to adjust with its single big knob. I don't have any relevant experience with alternatives.--AP</blockquote>
