I have the RRS MH-01 Hi-Capacity Monopod Head with B2-Pro II clamp. I have used it alone with the 600, but find that the sidekick gives me better control and I can sit in the blind with only a little tension on it and not worry about lens flop. It is especially handy when I need to shoot up into the canopy for birdies b/c of balance. I think the MH-01 only developed the wobble b/c of being rotated to 90 degrees and locked w all the weight on it. If you are happy w just the monopod head and the 600, you already have a simple solution. (I'm also tall and like the extra height of the sidekick on a monopod.) I'll post a photo of the set-up if you are interested. Cheers
