Longhaultanker was nice enough to offer to bring them across the border for me but I ended up buying from natural whetstone. Soft, hard and black in a 10x3x1" format shipped for a very good price and when asked about flatness I was told they lap them flat guaranteed before shipping them out. Which put a lot of my worries to rest. I also asked about their black translucent as they say it's there finest. I was told about a 200 US grit difference between that and the black but I'm sure the black will wear down fine enough to finish a razor on.

If their black isn't fine enough I'll order the black translucent from them. Such is life, move forward and be happy with what I get.
