Charles, the successful history of your ceramic bearing upgrade is precisely why I recommend the same for all except: 1. those with unlimited budgets, for whom I suspect that the LN Solution would be the way to go (in spite of the relative lack of vehicles on road to prove the technology); 2. those with the large single bearing who cannot upgrade the bearing without an engine tear-down. For those I would suggest that DOF lubrication of the original bearing, even if there are minor risks of aeration and oil pressure loss, would be better than leaving in the original bearing and hoping that it lasts now with just the removal of a seal.

I wonder, however, if a dual standard is not at play here. When LN introduced the ceramic bearing upgrade, customers installed the same even though they had not yet been proven in large numbers over a long period of time. They were convinced by the initial testing and the inherent logic of the design - something which you and others are now suggesting would be inappropriate for prospective customers of DOF technology. What is more, your new 'solution' is also not supported by a large number of installations over long periods of time. To remain logically consistent, doesn't that mean that the upgrade should also be preferrred to the solution because of its proven track record?
