Need help against Rage Collective !!!

[jc173]

For the first time ever I have had to research stellar manip and cut myself off from most of the galaxy. The Rage and the TDM Piundon are making a shambles of my empire's northern borders. I know the AI doesn't deal well with that so I cut it down to just one warp point entering the northern border instead of severing all contact. At least this way I can concentrate my defenses on one choke point.

Alpha Kodia:
The tatic of putting mine sweepers on the larger ships seems to be working pretty well for the Rage. Even when they don't make it through they can decimate a minefield that would stop most other races dead in their tracks. They lose their early waves, but they usally make it through if they follow up with more ships. Although part of this may be due to the face that I've let the two highest PD weapons have a limited mine sweep capability.
