Switzerland - Head Of The Valley
If you fit either class, consider the Arca Swiss head on this blog. It would be rotten to do sport with and rotten to do portraits with...but it is the world's best for panoramas. If you are into horizontal stitching and can determine your camera/lens nodal point, you can make this head spin on the vertical axis with a precision that will astound you.
It copes with the tripod being on uneven ground by the simple expedient of keeping the ball under the tyrntable. Do what you like with the legs under it, once you level the camera and check it with a spirit level you can spin round for a perfect horizon. Your stitching program will cope much better.
