I agree with you. The front ceramic bearings seem to have problems. At least the Boca ones... Perhaps it has too tight tolerances. I don't know if the JP FX engines have BOTH ceramics for the front and rear. If they do, then they somehow perfected the art to put the front ceramic bearing without anybody complaning about bearing failure...
