Oh wow. I'm not getting my hopes up, but a T5 Nova would be fantastic. My biggest regret as a science officer is that I flew a cruiser the whole time at LtC, so I never really got to fly one of those T2 sci ships. They're so cool.
I kept my Nova all the way through to Captain through sheer, unbridled fear of the Commander level golf balls.
Even now that I'm in the Intrepid at Captain, I do miss my Nova.
