I prefer to skip building heavy cruisers and use a speed buffed BattleCruiser instead, if you take modules that don't impact your speed stat and the highest engine you can out scout a standard cruiser (only take 1 tier for the following; BC armour, and Main Battery. For all the other custom slots you should put in dual purpose secondaries and/or scouting planes).
