do you have any idea what the Narn player will be taking? at 5 point battle I would as a Narn look at a good skirmish line of K'T's and Thentus, a shokar or two, then a couple of heavier ships to take the damage, G'Quan (and varient) maybe even a kabintak, and I am reliably informed that the G'Vrahn is Brutal.
Thereore, forget fighters unless you are sure he won't take anything with e-mines, Interceptors will be good to fight of that up close and personal feel the narn love so much, but you need something to take down his skirmish line (both for it's power and initiative sinking) I'd seriously consider a few Hyperions, they break easily, but the beamy punch could be enough to hit his skirmishers hard early on, the Nova can hold it's own thanks to good damage track, and it cvan really mix it up close (plus it does have fighters if his e-mines get negated) maybe just maybe consider a command omega for it's hefty beam, also think about the Hermes loaded up with flash missiles.
