I far prefer the edge on my Thuris finished with straight water. Some guys say they like a slurry edge but not me. On a JNat yes, but not on a Thuri. A matte or hazy mirror finish is not out of order if you used a slurry before finishing on straight water. 25 - 50 x-strokes on straight water isn't always enough to remove the matte/haziness from the slurry.
