Greetings Andy,
I apologize for the delay in response – I wanted to make sure I had the most information possible before getting back to you.
We understand that there is still a concern about the chosen design of the plate for the Canon 5D Mark III body, especially regarding the use of the “step” which has been referred to throughout this thread and why we deviated from the “curved flange” design along the back of the plate. We decided to use the rubber gasket for enhancing anti-twist. However, the gasket's irregular shape would cause the plate to tilt when tightened down. The best way which ensured that every camera body would align accurately was to set up a series of contact surfaces that would guide the body into level orientation. For the compound curves of the Canon 5D Mark III, we can get a more consistent result from utilizing flat contact planes than we can by machining a curve into the plate, especially when taking machining variances and tolerances of the different manufacturers into account.
Some people are concerned that the “step” will cause additional marring on the body of the camera. The changes made in rev. A include a small, barely noticeable edge break that was added to this step. It has made a world of difference in minimizing possible marring. Any plate, regardless of manufacturer, may leave some signs of wear at each place where it contacts the camera.
The gaps between the flange and body are the result of our engineers removing excess material after deciding that a taller flange in the back offered superior anti-twist. Leaving material there would not increase support or function in any way and is a matter if cosmetics. Most of our customers like and are happy with the looks of the plate. If you are not satisfied with your plate, we stand by our Return Policy:

Please let me know if you have further questions.
