The nice feature of the open-face BZ cab is that you can convert it to play RB pretty easily. Especially if you have a Braze HSS kit, as it eliminates the need to blue-wire mod the main board to add the extra ROM. Plug in HSS kit, swap the two graphics ROMs, swap aux boards, swap CP, add one jumper wire to get -22V over to the aux board, and you've got an RB.
