Thread: What is your favorite coticule?

At the risk of possibly highjacking the thread, could those of you who have years of experience with coticules comment on how to choose a coticule? . . . and don't get all jedi on me with "The stone chooses the user" or anything ;-) . . . I have a smallish coticule that I picked up from the classifieds just to test the waters and would like to get a larger one. Aside from size, are their qualities of the hone that can be gleaned from color, striations (inclusions?), etc. I have looked thesuperiorshaveDOTcom and they seem to have a huge selection. Thanks!
