My idea is the following:
Two or three big fleets made up of several dozen cruisers, to deal with any fleets of his in the area.
A fair number of smaller fleets, say 4-5 cruisers a piece, to assist in battles or planetary assaults depending on the necessity.
A boatload of small, expendable fleets, say 1-2 frigates/destroyers each, to pick off planets, using around 5 fleets per planet to increase success rate.
My problem is that my two homeworlds closest to this guy (dreadlock, if you want to look him up) are not producing much steel. Alpha Luriae has too little population and produces only about 2.5k a day. Alpha Capetiae has farm subsidies that reduce steel production but I can scrap it long enough to boost production again for a while.
