I have had the best luck with the round. Cbid usually has them for fifteen with the quickbuy, less if you bid. I have been doing the salt test, but lately I have been thinking about calibrating them with beads in a tupperware. It takes a little longer to level out, but I found that they are always dead on. For the record, I use heartfelts, but I have heard nothing but good things about the clay.
