......the only slab to trust (drum roll here) are the ones with a CAC sticker! reply to panamagold thread.
Interesting. MFD just told me that CAC has had a fundamental change to the definition of what their stickers mean. I never got interested in CAC so I don't know what the before/after differences are. But if I understand correctly a sticker use to mean above average for the grade. Now it means average or above for the grade.
