Can anyone recommend any sliding bridge plate / dovetail / rods combinations that would work well with an SR3? I know Arri offers the BP-6 and BP-7 systems, but I'm looking for something a little less expensive. Ideally, I'd like a bridge plate that also has the anti-twist registration pin to help prevent the camera from rotating when mounted on the plate.
I do realize that the Arri bridge plate systems are adjustable between R16 & S16. That said, would use of any mounting system other than a BP-6 or BP-7 result in incorrect rod alignment for a camera in S16 mode?
