Instead of the quarter set from Whipped Dog, I decided to just get the Norton 4000/8000 combo stone, along with a DMT 325 for lapping and restore/bevel setting. If I can't set a bevel with the 4k, I do it with light pressure on the DMT.
I also recently purchased a ~15k Welsh slate stone from AJ on eBay, and it works wonderfully. Truly great, smooth shaves when I finish my blades on it. I am extremely happy I stumbled upon his listings when I was looking for a finisher. Saved me nearly $50 because I was originally going to go with a Naniwa 12k. Now that this Welsh stone works so well, I don't see the point in bothering getting the Nani.
So while the quarter set seems like a good idea, it really isn't when it comes to what you get and the inconvenient size of them. I'm glad I listened to folks on here when I posed the same question. Still love Larry though. Anyway, the Norton lapping stone is sort of a joke I see according to reviews, and how often would you use the 220 stone for restore work? Seems like a better value overall to get exactly what you need with a good lapping plate such as the DMT 325 (which can be used to lap any stone I'm assuming) along with the trusted Norton 4k/8k. Then once you master shaving off of the 8k grit, find a well priced finishing stone, such as a vintage coticule, Chinese 12k (a good one, not a fluke), or a Welsh slate stone. I really feel that the guy on eBay (AJ I believe his name is) is right on the money with the product he is selling. Mine works amazingly and his reviews are outstanding. And he'll give you a good deal if you message him. I got just the 6"x2" ~15k grit stone along with a small slurry stone (which works well to build up a milky slurry) for only $30 shipped. He was wanting $85 shipped for the set of 3 different grit stones. With shipping from the UK for a friggin' somewhat heavy stone, that is an amazing deal. I strongly recommend everyone try at least one and see what they think.
