I have use the Bogen RC2 QR plate for all my cameras 35mm, Mamiya 645, C330, RB-67, and 4X5. It has worked for years, I feel the camera could be a little more stable (4X5 and Rb-67) but all my pictures have been very sharp even in long exposures (1-15seconds). I use the 468 ballhead on a 3001 tripod. I might upgrade to the 488 ballhead but I,ll keep the RC2 QR plate because I have so many, I also might upgrade the tripod for the larger camera but I never get around to it.
I think the plate you are talking about is the RC2 plate
