I bought some of the Budda Bearings. I bought stainless, hybrid, and full ceramic. With a flick, the stainless spun the longest, and the full ceramic the shortest. I had thought to post here asking if they just need breaking in, but the stainless spin so well, I don’t even care. Wish I had just bought a boat load of stainless. A good stainless seems to be more than good enough.
