We can get you a Snow White WEPS stone. 😉
Personally, I have placed my 8K Snow White between the 5K and 10K Choseras on my other progressions. It’s not completely necessary – it’s a matter of fewer stones with more strokes, or more stones with fewer strokes, but I find that the 8K snow white really does clean up the 5K very nicely for the 10K.
