Go the Calico route, very good bearing proberbly the best. Bearing mfg. have changed their coatings over the past couple of years, the cosmetic coating that was on most bearing was found to gall the crank their for eliminated. I have also found that the quality has suffered, sharp edges, burrs, and tolerance differances. Callico fixes these problems with their prep process, and gives you a dry film that holds up very well if the bearing is starved for oil, or if the oil gets airated.
