Wiz,
You will be rated for all the 73's I believe. An -800 just arrived and I guess the rest are a mix. The 73's are currently BOH, CVT and DSA. But we know on the inside they will be appearing at a major airport(s) near you soon.
I am of course no expert, Im not on that fleet, as the 73 is not robust enough to take my landings.
