Bob, Have you ever actually seen the drawings I have done showing my design? One quick look should tell you all you need to know about how my design promises to be a VAST improvement over the Kadee design for centering.
Go to http://www.trainweb.org/seaboard/SScaleGearBox.htm and look at the images under the "PROTOTYPE PHOTOS AND VIDEO" boxes and the "FINALIZED DESIGN" boxes. When Kadee couplers swing to either side, they also slide forward in the gear box. Also, when you're pulling a train, the coupler pulls out of the gear box and the spring in the shank tries to pull it back in causing the cars in the train to go react like a slinky (looking like the train is held together by a rubber band). My design COMPLETELY eliminates the shank spring and it's slinky effect. An added bonus of my design is that you don't have to deal with installing the shank spring... all you have to do is drop in a small, plastic block into the shank. The flat spring that replaces the coiled shank spring just drops in place and is sandwiched between the rear of the coupler and the gearbox's inner feature, making it MUCH easier to assemble.
