LV has two new waterstones in their catalogue -- The Bester/ Imanishi (spelling?) and the Sigmas. Anyone have any experience on how they stack up? Compared to the Naiwa superstones and/or Shaptons. I have Nortons and am thinking of trying another finishing stone-- Hopefully something that doesn't require as frequent flattening. I have 01 and A2 plane irons and 01 chisels.
