What do you guys recommend to assist with taking shots for panos using the cube, with the set up rotating around the nodal point? Do you use a specialised pano kit of some sort? Or put some sort of rail or plate into the set-up? I have seen reference to the use of a Kirk geared rail plate or a RRS Focusing Rail... Any advice?
I will be using a Pentax 645D with some pretty large, heavy lenses (including 6x7 ones), so the set up would need to be capable of handling that. Don't want to spend money on a great tripod and head, then end up with a lack of rigidity due to the wrong plate/rail.
