Yes. The chap who I know who inspected my bubinga ply type shell drums when I first recieved them who makes custom basses told me that my drums were AA flame bubinga as indicated by the specific visual appearence of grain grade bubinga based on the quality of the visual grain seen on the inner and outer plies chosen for these all bubinga 9 ply drums. Unix probably has a much better handle on the detailed terminology of all of this related to various wood grains and specifically different grades and types of bubinga wood in this case.
I know that i've seen several types of bubinga grain pictured in kits on the DW forum including this very lovely kit in this thread so this must be the case. Probably different species of bubinga wood too adding into the visual grain type mix as well as various grades of wood grain chosen as you and others have seen.
