Thanks for the suggestions guys.
I've been agonizing over a class name for days now. For some reason its really important to me, because it really, in a way I think, can make or break a ship. When I named the Century Class, I got lucky because I found a name that hit a few key notes... 1. it was of sufficient grandeur without being overbearing, cheesy, or overly self-important. 2. No other ship in ST had that class name. 3. It suited the elegance of the design.
The design of this new sip is quite different, both in terms of aesthetic and intention. It's a little edgier, but not overly aggressive. Where the soft lines of the Enterprise F really lent themselves to a soft and elegant name like Century, this ship is designed to look edgy and forceful, like it's leaning forward and ready to go. This ship, in a sense, is a Pontiac, where the Century was more like a Buick.
Anyhow, the Class name I've decided on is Eclipse. It meets the same criteria as mentioned above, and to me, is well mated in its meaning and tone to the design of the ship.
Some other names I strongly considered, but rejected were...
Magnus Class -->Too Latin
Theseus Class -->Greek, which is overdone and cliche.
Odyssey Class -->same problem
Valiturus Class -->So Latin as to be a bit pretentious.
Nobel Class -->Too subdued, but would have been easy to name ships of the line after Nobel winners. I think I'll use this for a future series of science ships.
Hood Class --> Pays tribute to a British Admiral whom to me, doesn't stand out as a Prime example of a stand-up 25th century person.
Indefatigable Class -->Actually I really like this one, but I'm willing to bet a lot of people out there don't have a clue what such a big word means.

So, Eclipse Class it is.
I'm aware that there is a Star Wars ship out there with the same name, but there has never seemed to be any problems with that kind of thing before. I certainly can't foresee anyone saying "but Star Wars has got a lock on this one!"

I'm eager to read what you guys think of the name.
