I prefer the Naniwa's over the Shapton. I get much better results. I am sure there are others that will prefer the Shapton's. I find the total results better with the Naniwa's and I like the feel of the blade on the stones. Really what gives you the best results. I go from my 12k Naniwa to my Escher for 5-7 laps under water then to my Mastro Live Loom strop. I find this combination to really give me the best results.
