I was in GGGT early this week and I talked to blake and we talked a little about wizards. GGGT got in some original mold wizards from like 2002 i think he said where it just says putter on it and has some dots. He told me this wizards was money, but for drives not for putting. He told me it was a hair more stable and I can tell. The things works great for driving!! I highly recommend. Next time I go back i'm going to get another one. He told me they had some retooling with slight variation and the new one is most like the original that he fell in love with. So I know that was some retooling, but what the differences are I couldn't tell you. I hope this helps.
