I agree about the 220 Norton/Naniwa comparison. I think the reason that the Norton works better is because it is so soft, maybe even too soft, that the slurry ends up forming sort of a paste. Because it is constantly releasing grit, it is also constantly refreshing its surface. The Naniwa 220 is relatively hard and seems to load up quickly. It cuts great right after lapping it but it doesn't continue to cut the way the Norton does. I try to move up to the 400 as quickly as possible after the 220.
