From #40 to #31,the Marvel Omnibus that i think would be awesome would be:
Captain America by Gruenwald (This went from 56th place in last year most wanted Omnibus Poll to 38th this year)
Spectacular Spider-Man Omnibus.
And maybe New Warriors Vol 2,i read more the first stories that the stories that would be in a second volume,but this looked like a comic book that kept being interesting.
