Jim, are those 40 issues from the beginning of his run and sequential?
Yes. They have issues #331-#373 up there. If I'm not mistaken, that's the first 42 issues of his run (*unless there was a fill-in or something he didn't write— I haven't read David's run on Hulk).
I had the Marvel digital servise a couple of years ago. I liked it but had some dislikes too. One of the biggest problems that I found was that runs like this were spotty with gaps in issues. They may be better about this now though.
I joined for a month back in March and found that still happened with some runs but they seemed to be filling in the gaps.
