Well, I gotta say, this topic (the humble bearing) can be one heckuva rabbit hole! John, this is likely why your Chris King's are probably still going strong - go here <https://chrisking.com/pages/technology>, scroll down to "Our Bearings" and watch CK's video.
CK manufacture their own sealed angular contact bearings. Amazing since CK can then control each and every aspect of all of their components. Makes complete sense. It appears that WI has partnered with Enduro Bearings. It would be an interesting exercise to convert from radial to angular contact bearings - yet another project! I have to say, I'm hesitant to try since I'd likely have to buy or borrow more drifts and tools. I recently serviced my rear hub for my Rambouillet (Shimano Ultegra FH-6500). I think that hub was introduced around 2002-2003 or so. I bought the Ram from a fellow RBW person on this forum and it was ridden well. After disassembling the hub it was in very good condition. I cleaned out the cup and cones and used Shimano's "Premium" grease and it buttoned up nicely. Amazing longevity. Those cup and cone angular contact bearings last a long time.
