Well, not sure if this adds anything to the issue of CRK and mammoth. I ordered a set of mammoth bark CRK's (Lg, sm and Mnd) about two years ago. Initially they said it would be six month wait. Then they said it would probably be another six months. After that when I called to "check-in" they said "we still have the order and it should be ready in the next 60 days". That was about a year or so ago. I've kind of given up on the order and no longer call to inquire, since I can't really rely on the answer. Maybe some day CRK will complete the order, but I kind of doubt it.
