|The Italian Battleship Roma|
I got a 2" hex cloth from Magister Militum at Salute and am now planning to get some Figurehead 1/6000 ships. (1/6000 would be a logical step down in scale from my 1/3000 pre-Dreadnoughts.)
The most appealing commercially available rules I've found so far is Grand Fleets, but I'd prefer something simpler like DBSA.
Being very small and hard to recognize at playing distance, I would definitely want to put the ships on, say, 25mm x 50mm bases which will have enough room for clear labelling, even if it's just an ID number.
A small fly in the ointment is the Figurehead destroyer bases which are moulded on and will have to be countersunk into the MDF layer of my larger MDF-and-steel bases.
