Forgive my total newbiness shining here
With some many spending in components which add to + attack roll, just to be able to get -50% malus to the to hit, why not reverting to missiles and fighters equipped with torpedoes?
Also, does ramming has a chance of missing if you get into his square? if not drones should be nasty with their to hit malus and good staying power?
I suppose the best to do is having the 3 kinds of weapons, to saturate his PD (which he has perhaps not in number btw).
