Bob, I have an Arca Swiss B1 ball head on a carbon fiber tripod that I use for all my other systems. I'd like to be able to pop the Sinar on the same setup. To do what you suggest would mean removing the B1 head because it has the Arca clamp permanently attached...ideally I need an Arca plate that would screw into the bottom of the Sinar's tripod mount. I called Kirk Photo yesterday and they have a 4x4" rubber coated Arca plate they recommend for LF.
