Best ship size?

[Alpha Kodiak]

For the most part I like light cruisers into the midgame and battlecruisers later in the game. There is room for other sizes, both on the smaller end and the larger end, but the bulk of my fleets wind up either LC or BC. The least used size (for combat roles, anyway) is probably the cruiser. It doesn't give you much more usable space than an LC, after the double life support and crew quarters, at a greater cost.
