I want to save a couple clams and get a set of stones to start. Should I get the Naniwa SuperStone 5000/8000/12000 or the Shapton Glass 4000/8000/16000? They are both about the same price. I like the splash and go stone. I know I will use them more if I don't have to soak them first, like the Norton. I am open to other suggestions also. You guys are the experts.
