1. The Flash
For 2 and 3 I want to say "Titans" and "Teen Titans", but I'm not completely behind the creative teams. Titans, I like the writer, not so keen on the artist - don't think he's the best fit for the book. Teen Titans - the art looks great, but I'm unfamiliar with the writer, and haven't heard any positive word-of-mouth about his Green Arrow.
So maybe Wonder Woman and Trinity. Or Batgirl. Or Blue Beetles.
