I'd say Doom Patrol if I didn't already have Mayhem
I just started reading JLI, so I have faith. Though, I don't know what else Giffen has written lately
JLI is awesome and I love GIffen's old stuff, big Trencher fan here, but his recent stuff Blue Beetle, Ambush Bug, Tag, etc... has been less then stellar.
