Just to give you fellas a heads up on what's to come, pictured below are all the different types/layers of Coticules (including a Kosher, or Kosjer stone) from the ONLY source of coticules in the world (whichever retailer you purchase a coticule from, anywhere in the world, unless a vintage coticule comes from this source).
I'll be trying out the different types/layers of coticule, as well as some "bout" stones to find out the following.
1.) How does each type/style perform?
2.) What is the best type of coticule for the $?
3.) What is the best type of coticule regardless of cost?
Pics, Pics, Pics....
