My current list is down to just 8 monthlies -
Batman, Batman and Robin, Detective Comics, Brightest Day, The Flash, GL, GL Corps, GL:Emerald Warriors
I'm also buying the Return of Bruce Wayne mini and will probably grab the main Batman - The Return 1-shot (but not all the tie-ins fore each bat-title). Oh and I'll definitely pick up Grant Morrison's Batman, Inc. when that starts later this year (I already dropped Red Robin to make room in the budget for it).
Much like with collecting, I admire your restraint. I've been working on trimming down my monthlies as well, and I need to get better at that. Much like with collecting Star Wars/etc. it is tough to find both the budget (especially with $4 books now) and storage space for so many, as they start piling up.
As I mentioned earlier, I get most of my Marvel books via subscription (stemming back to a time when we didn't live anywhere near a comic shop), and that makes them much more affordable too (about $1.67 an issue I think). With that, my current subs look like this:
Avengers (Avengers, New, and Secret right now)
I've also been reading/checking out books like Wolverine, X-Men, and Daredevil off and on, and pick up any minis or "events" at our local shop (like Shadowland). For the DC stuff, my list is very similar to Jeff's:
Batman and Robin
Batman Inc. (upcoming)
I was reading JLA, but just wasn't enjoying it that much. If/when they get better stories and back to more of a "big 7" lineup, I'd likely pick that up again. Teen Titans is another book I like, but haven't been interested in lately. I'm on the fence with Finch's upcoming "Batman: The Dark Knight", I may pick that up as well. I also like GLC, but have tried to stay with just the core GL book for now. I've also been picking up The Return of Bruce Wayne and Batman Beyond on the mini side of things.
Other than that, the only other title (and only non Marvel/DC book) that I'm getting is the recently (re)launched GI Joe: Real American Hero. I'm really enjoying it so far, but I'm debating on whether or not I should wait for trades on this at all. Not a matter of not liking it, but just trying to trim the pull list a bit. Ideally, I think I should keep the number of titles to around 10 monthlies, but just haven't been able to make that many cuts yet.
