I've spent a lot of time looking for an ultra-light panoramic head for hiking when weight is critical. Not spherical, but round. I found a few but they were all in the $300 range. Decided to try this one and was very satisfied. However, the pitch was too loose when I got it, so I added a friction washer to tighten it. Also, some might find the swivel knob too straight, but you can bend it in a vise, I did a bit to avoid contact when using the binocular adapter. For a 0.5lb pan head, that's a good deal.
