I think that I'm disappointed in them a bit because I was expecting them to be as clear focused and determined as Head!Six. Not to squabble like children. I think D'Anna and Cavil are the strongest of the seven. Wish we had seen more. How did it slip away from Boomer and Cap!Six?

Hm, good point. For so long the only 'cylon' we saw up close was head!Six, and it was easy to think of her as representing all of them... but she's/it's not the same as the actual cylons. Cavil was pretty hard-core, you're right, and the Threes, since D'Anna had the season three cylon storyline... but Six and Sharon were the reason for being on New Caprica in the first place. So yes, we should have seen more from them; instead they just whined to each other about feeling unloved.
