Thanks for the recommendations, Ron!
The Arca-Swiss "double pan" refers to having the usual standard panning base on the bottom
and another one on the top, above the ball. I cannot find a large ball head that doesn't have the panning base on the bottom (as well as rotating the ball)! My whole quest started because the Markins panning base "slips" when under the kinds of loads and torque I apply (not excessive, but 3-5 kg of weight).
Coincidentally, I was at the major photo-gear expo here in Toronto this past weekend (rain killed my other plans) and got to try out many different "large-ball" ball heads, both the ones the on display by the distributors and dealers, and from some friends and even a random guy walking by! Not side-by-side under the same conditions kind of testing, but at least I got a feel for each of these:
Novoflex Classicball 3 (they didn't have the larger 5 I'm interested in): Extremely well made and finished, seemed bombproof and silky smooth, except the panning base was achingly difficult to rotate. Could never use a Wimberley Sidekick on that! They are checking with the folks at Novoflex Germany to see if this is typical of the 5-series as well...
RRS BH-55 (thanks Nick!): Well-made, silky smooth,
very nice panning base, and I love the look/ design. However, the "dark grey" finish didn't look very durable (but maybe Nick uses it as a weapon), and the control knobs felt loose which apparently is just "how they are." Also a surprisingly wide and heavy sucker! However, that's just for comparison, as I won't buy from RRS for personal/ professional/ moral reasons.
Kirk BH-1 (thanks random guy visiting the OPC booth!): seemed taller than the rest, and kind of "brick like" both in controls and build quality. Might just be the one this guy had, but every knob was hard to turn! The ball action was incredibly smooth (better than the RRS, almost as good as the Novoflex) when you got the right tension on it. Oddly enough, the owner said he was likely going to get a smaller head because the BH-1 was overkill for his needs, and he asked me about Markins!
Manfrotto MH054 & 057: Really big & heavy, yet they also felt rather cheaply constructed compared to the others. Smooth ball action (which my older Manfrottos lacked), and easy to grab controls. The version without one of Manfrotto's dedicated quick-release systems is "special order!"
FLM Centerball 58FT: I had only heard of FLM in Europe, but now they are available in North America. Interesting ball heads, made entirely from CNC machined aluminum on the outside - even the (multitude of) knobs! (Silver and black finish like the RRS, but they looked a little rougher and kind of "blingy!") However, the ball action on their heads is incredible! Very smooth and solid feeling, with a great "tension memory" function unlike any I've seen on other heads. They also have a "tilt only" function which locks the ball into rotating on only one axis (like a gimbal when used with the panning base), and a really nice "click stop" button to turn the panning base into an indexed panoramic rotator!
Note that all of the big-ball heads I was able to look at, touch, and try out were not from Asian manufacturers. (There were a few Asian manufacturers represented, but only with their smaller-ball heads) And no trace of Markins, Benro, Sirui, Photoclam, or Feisol... kinda weird!
