Hi,
I also much like the Arca Swiss D4. It's a pleasure to work with. I use it with a leveling base. The Arca D4 has rotation on both the base and on the top. Rotation on the base does not cause tilt if the base is level, that is a good thing for panos.
I didn't really like the Arca Swiss fliplock so I replaced it by an RRS lever type QR (it's very easy but you need a 3.5mm hex key, it's standard but not commonly used). I moved the fliplock to my video head, so it has found a nice reuse
Ellis like the screw type QRs from RRS and I prefer the lever type, but all my plates work well with lever type QR.
Before going to RRS I used Acratech, they also make good stuff and have a nice looking QR. The Acratech screw type QR actually works very well, but I had problems on my Acratech head that I could mix up QR and pan knobs, which quite often lead to a camera sitting loose in the QR. That is the main reason I switched to lever type.
The camera I use is about 2.5 kg with lens. Working on a RRS BH55 head for a couple of days I got pain in my wrists, with the D4 I can shoot for a week with no problems. I'm persnickety with composition and getting it exactly right with a ball head is not easy, and a ball head has always a tendency to shift when fixing the ball.
The D4 has only gears on two axis, I would prefer gears on three axes, but horisontal locking precision is very good, so I'm quite happy.
Best regards
Erik
Clamp alone for adding to an existing head : Really Right Stuff PCL-1 http://reallyrightstuff.com/ProductDesc.aspx?code=PCL-1&type=0&eq=&desc=PCL-1%3a-Panning-Clamp&key=it
Once you have worked with a panning clamp at the top as well of the bottom of a tripod head you understand why it makes so much sense especially for table top work.
Arca-Swiss B1 Monoball or the RRS BH-55 - either one with a Really Right Stuff PCL-1 panning clamp in place of the stock clamp.
The Arca-Swiss p1 is terrific and so is the p0 but although they have a panning camera platform they don't have a panning joint at their base.
Rational (two way tilt heads):
I suggest you look at the Arca-Swiss D4 and C1 especially as you are asking about table top product work. Being able to control fore/aft and lateral tilts separately can make still life work easier and both of these heads have panning platforms at the top as wel las the bottom of the head. For a much heavier duty solution I use the Foba ASMIA http://www.bhphotovideo.com/c/product/247458-REG/Foba_31_0118_ASMIA_Double_Pan_Tilt.html with a PCL-1 on top.
An ASMIA has a range of movement (even a ballhead) that no other tripod head can hand will hold even a big DSLR (Phase One , Hasselblad H, Canon EOS 1D/1Ds , Nikon D3x, etc.) very securely at that angle. Why? It was designed to support 8x10 Sinar P2 cameras. ASMIA heads show up on eBay from time to time and that is where I bought mine.
