Yikes Steve, take care of yourself, glad you are feeling better. I kind of thought the 55 would be your recommendation, but I wanted to make sure before I bought a 500 dollar boat anchor. My Gitzo sticks should be stout enough. I just want something when I'm in tight quarters that will facilitate going vertical, and I want to have the correct components for multi shot pano's as well. I guess I need that nodal thingamajig too.
Single row panos require only one axis of 'nodal point' adjustment, fore-and-aft. Multi-row panos require that you be able to adjust the entire camera/lens combination, in pitch, about the nodal point as well. Mine is the single-row kind: it's just a slider on top of a panning stage and clamp, so you can adjust the camera/lens fore and aft. It also has a spirit level at one end of the slider and another on the panning stage: the spirit level on the ballhead's clamp is obscured by the pano clamp but otherwise the two are redundant.
By the way, using the spirit level on top of the BH-55 with quick clamp normally requires that you dismount the camera; it's pretty much hidden by the RSS L-plate and the overhanging camera body. It's really the only design 'miss' in the whole system, in my view.
