I have also produced siege cruisers, but mine are armed primarily with mesons for two reasons. First, the don't suffer from atmospheric attenuation. Second, most PDCs have enough armor that they take an annoyingly long time to kill with normal weapons. HPMs are also a good choice, as they tend to disable the PDC faster even than the mesons.

Another important feature is the D-1 decoys. These are useful for soaking up the AMMs that certain races like to fire at you. Move into range, and wait for them to stop firing. Then pull the decoys into the hangar, wait 5 seconds, and deploy them again. The missiles will lose lock, disappear, and then the whole cycle starts again. Actually, if you have better ECM than they have ECCM, there will be points where they can fire only on the decoys, and not on the carrier.
