Posted this on Panoguide already. Someone suggested I post it here. Here it is.
The Nodal Ninja Ultimate line of tripod heads has changed the way I do panorama pictures. I used the R1 with a Sigma 8mm f/3.5 lens and a monopod while on the road. I must have taken that lens on and off the head at least 20 times a day. The panorama head performed flawlessly. The rail stop and the spring plunger work great. I do not have any excuses for not taking my panorama gear with me anywhere.
After I got back home I started using my NN3. It occurred to me that mounting the camera body to the upper rail was not as efficient as mounting the lens clamp directly to the upper rotator and totally eliminating the upper rail (well, almost totally). After adapting my NN3 to use the ring clamp I took a look at my Nadar bracket. Previously I had to have the pano head on a quick release plate so I could remove it from the tripod and snap in my Nadar bracket. It suddenly became obvious that using the lens ring clamp for the Nadar bracket made sense. I then saw that I could mount a Nadar bracket directly onto what was left of my good old NN3 and eliminate the quick release plates from under the pano head.
It is lightening quick to move the camera from the pano head to the bracket and back. You only need to move the tripod 11" for an absolute clear Nadar shot. Combining the two images in Photoshop prior to stitching your pano is brain dead easy. You could also mask out the tripod parts in both pictures and bring them into PTGui, stitch as usual.
