not really true silent predator. there's plenty of anzio/caen servers out there and most of them have a hard time keeping full.
cherbourg, harrington, argentan, etc, have been used in numerous different tournaments and cal leagues. So they are not "unknown" maps. in fact, players who have been playing DoD for awhile know them very well.
As for keeping a full server, it'll take dedication from our regulars. with any map, really. It's gonna take regulars to seed the servers, invite people to the server, dedicate time to the server.
so pick the map you think would be most fun, and get in there!
