Interesting - as I was reading your post I was thinking of a Berlebach. I have a 3032 which I like very much and it might work for your purpose. Neil's caution about the weight is important though - especially with wood. Although wood has a good reputation for vibration damping, it can also be very springy. If you overload the Berlebach, it will be particularly sensitive to torsional vibration/movement and it won't want to stop. Though it's rated for 26 lbs, I found it unacceptable above 16 lbs. Since you're taking panos with a fairly heavy rig that will iteratively pan and stop you may be pushing beyond it's limits. If weight is not an issue, something like the Uni 12 is probably a better bet and still less than carbon, but you would likely have to order it directly from Berlebach.
