I've just bought the Pro2 head for my 600F4. The build quality seems to be very good. Weight wise it is very similar to the Wimberley II. I do not have a problem with the pan and tilt knobs located in opposite sides. I have the curved arm on the right hand side and use my hand to control both the pan and tilt knobs.

I like the "lock" feature that prevents the arm from tilting while carrying the setup.
