Thrice, that second image is awesome! OThers very nice as well, but I am in awe of 2.
I\'d be glad to share the info on my setup:
My RRS plate is stamped 36. It has a slide screw on it, so I expect it was my universal I purchased, it has a slight lip that fits the X1 perfectly. My head was part of this dual flash contraption I bought from a guy once, that had been custom fabricated to mount a DSLR on it with dual flashes on arms. I found the whole thing to unweildy to use, so I stripped it and took the ballhead and clamp for this setup.
Ballhead is Manfrotton 484RC2, a very small ballhead, as you can see by size of clamp relative to it. The clamp is a Kirk screw clamp. The monopod is an older Gitzo CF pod, number 1568 Mk2. Perfect size for my X1 rig. :-) I can look up the RRS plate if you need me to.
