We are not in our best condition for the moment so in my opinion we should stick with Dust2 Only even that i would love to see more maps in DM. I think we should wait till DM gets full again then we can consider adding new maps even that im sure that adding new maps will make us loose players. We had a DM second server with 4 most popular maps in cs: inferno, train, nuke and dust2 and it was always empty anyway we can give it another try

.
When you add new maps , the server its not stable with players (i mean its not always 31/32 like its in Dust 2 Only) , thats because some player like to play in de_train some other hate this map and leave , thats what happens with other maps too. I remember Classic server for example , we had (dunno if we still have it probably we still have it) a very popular map like aztec , as soon as this map started players left and the server was empty till the map changed so im pretty sure this will happen with DM too if we add new maps.
Sorry about my bad english , living in Italy is making me forget it
