I desperately want to start reading the Ed Brubaker run of Captain America but all of my research is for nothing because I can't figure out what to start with. The Omnibus is too expensive so I can't get those. I have read the Winter Soldier arc. I've read conflicting things saying it's the beginning of the guys run, but it's starts at issue 6? What are the trade paper backs I can start collecting to read the run in order?
