This is my new favorite Momo steering wheel. I ordered one when the Model 78's were on back order and ended up loving it. We have been using Model 78's for the last 10 years on everything we built and owned. The Model 69 is about 1/4" overall diameter thicker than the Model 78 which makes it a lot easier to grip with gloves on. The Model 78 has zero amount of dish, so it it perfectly flat and the Model 69 has 3mm of dish which equates to roughly 3/32" of dish which is hardly even noticeable. See attached picture for a side to side comparison of the Model 69 and Model 78. This is basically a Model 78 with a thicker surface to grab.
