Steve,
Are you planning on building jump point defense bases, something along the lines of the sentinel planetary defense base, but with something like the weapons of the battlecruiers, but only limited engines--one or two engines would allow the wp defense base to self deploy. I would also give them something like a machine shop from SF, to allow for quick battle damage repair, or sometype of docking ring to serve as docking stations for your corvettes flotillas. That way you could contest hostile entry into a star system. Something on the 10K size with ASM launchers, rail guns, AMM launchers, sensors, etc., docking base, repair facilities to maintain a flotilla of corvettes would be ideal. Ideally energy weapons would be useful in a warp point defense role--don't have to worry about ASM missile launchers that way.
