Hmmmm, Natural stones vary ??? Wow what a concept...
We have argued that for years on this forum, or "The wonderful world of finishers, what we all argue about and waste our money on"
The added dimension of using a finisher is the Guy pushing the steel across the stone, so now you just compounded the variables
I would love to test a "Bad Zulu" myself so if anyone stateside has one that they wouldn't mind parting with for a bit would PM me, maybe we could arrange something
As I have only tested two and both seemed fine to me, the first one I tested I ran over 100 razors on and the second one I used at a Meet on only a couple...
ps: Full disclosure I did not run out and buy one, I need another finisher about as much as I need the 8 inches of snow that just fell...
