			If you have a survey, it should be divided into three surveys as the characteristics of the three generations of bearings is quite different. And since LN has 3 ball bearing SKUs...single, double and Single Pro. 
 
As for some background on loose or looks/felt fine original bearings that were removed, do a search using the forum search function for IMS and JFP as he runs a shop and has done a whole bunch.
