Getting back into my Hulk comic phase

I’d read the Immortal Hulk run several years ago, but I don’t think I finished because I use a free library app that hadn’t updated the entire series at the time. Just checked and it’s now updated so I think I’m going to reread all of them again! And I just read Gray Hulk today and it’s so good, I love how they showed Bruce’s backstory in that one.
