I'm currently reading the awkward period of Justice League post Giffen/DeMatteis and pre Morrison. Right now I'm on the verge of finishing Dan Vado's 14 issue stint on Justice League America. It's notable for introducing Booster Gold's (awfully dated) armor phase, the third incarnation of Amazing Man, and Ice's family.
Dan Vado is one of those writers who's life is more interesting than the story he tells: He is the founder and publisher of Slave Labor Graphics, and judging by interviews, genuinely had a passion for the Justice League.
