I'm digging Captain America right now, too. I especially liked him in Secret Avengers, but it seems he's kind of phasing out of that one. But there's something about how most of his enemies have Nazi ties that is just really cool to me. The good old red, white, and blue, kicking Sins butt is cool. And Sin is hands down one of the most evil villains going. Or is it villainess.
And I like the new Winter Soldier book, too. I'm kind of in an espionage/black ops/CIA phase right now, so I really dig it.
