I have an FLM Centerball 58FT too, use it for my RB67, it's not that heavy really, and very strudy and good value for the money. I have to say that I get on with both ball and pan and tilt heads, and use the manfrotto one in the picture too. It's a very personal thing. I've tried lots, and have to say that not one of them has made me go 'wow'. Most good brands (manfrotto/bogen, gitzo, novoflex FLM etc etc) will do the job of holding the camera steady, it's the ergonomics of where the knobs are that you need to try out first, what works for one may not work for another.
