That was a great explanation Mark. That's actually why I'm not considering any disc with polyurethane inserts. At my age (52) my spine will degrade naturally over time. All of the angles will be altered even if only slightly. The poly cores will not react well to that I fear.
That is one of the properties that makes the Maverick more appealing to me. With a single alloy used in both inferior and superior components, sheer wear is nearly non-existent. If only they offered a zerk fitting for lubrication.......
I had actually emailed Justin when I saw the inverted plate. Thanks for clearing up the mystery of the symetrical endplates.
