I'm currently using a NN3 with an arca-swiss compatible clamp on the upper rail, so I can easily mount and dismount my camera from the pano head.

I'd like to switch to an arca-swiss compatible system that clamps the camera in the exact same place each time. I want the system to be accurate enough that it could be used for batch stitching with a better pano head in the future.

There are a lot of different NN clamps and plates, and I'm not sure which one(s) would be suitable for me?
