Have you considered the Romulan ZPM vs. the Tachyokinetic?

The tachyokinetic converter is already in my build. 

The ZPM is really not that great, honestly. At epic (which is what I have it at), it only offers 2.2 subsystem power bonus, 24.6 starship power insulators (resist shield drain/energy drain), +2.2% critical chance. I had it in my build and didn't find it made much of a difference. It doesn't really do anything to directly effect DPS other than the power level boost, which I already know will make all of a 1.68 point diff. in damage per weapon. Not really worth it.

I have a feeling the only thing that will make a diff. at this point is to either respec and push more into my admiral level combat skills or push toward epic weapons, which will be excessively expensive.
