Maryland its a great ship... a lvl 75 monty...
for indy i would consider using the triples from Sodak and just use it as a higher lvl-boosted dp SoDak.
another configuration could be using only the 2 front main guns, maybe playable as an AWhore ship? could be? with US terrible deck armor?
well, its a chance... i might get one some day, but it would be just for fun&test..
to lvl a crew you should use:
atlanta (AA) > Cleveland (AA) > Baltimore (AA or Gunship) > ALask... (HELL NO! just kidding... keep on baltimore up to the Colo) > Colorado > MARYLAND > MISSOURI > Monty > Nebby.
maybe getting an EBB1 or a PCA (don't need to buy a PBB just for a couple of lvls) to help in those "long" lvls from 58 to 65
