No love for the Ant-Man book? Much as I like Squirrel Girl whenever she's appeared I'm not mad confident about having her own book (because I'm not super sure she can carry it, her 2D nature as an inexplicable Mary Sue was one of her charms, actively examining how she achieves her insane victories might take some of the gloss off.) First issue was pretty OK, don't get me wrong, she handled Kraven beautifully but I don't think the charms gonna hold.
By contrast, I genuinely loved the Ant-man book, at least more than Grayson. Lang may not be the most interesting Ant-Man but he's still got the most heart behind him with the relationship he has with his daughter and how much being a dad out-weighs being a hero. Shit, he's quite possibly the best dad in comics. By contract, Pym's got 'the mother of all fuck-ups' as his biggest element so you'd kinda need his series to be just him trying to stop Ultron, which is basically Avengers AI, and O'Grady... kinda ran it's course. He even had a big redemption moment and then backtracked it.)
