Hi: I am considering picking up an escher or thuringian and am hesitating on pulling the trigger on a stone north of $400. There are these 1.25 inch wide x 5-6 inch long ones that come up, which are more economical. This seems narrow, but can this work for one long term if it is being used only as a polisher? Or should I ante up for a larger one? Wondering what peoples experience with this width are.
