Thanks for all the replies.  I've decided to skip Excalibur between Claremont and Davis' runs, and skip Wolverine between #10 and the beginning of Hama's run.  I think I'm going to stick it out with Uncanny, X-Factor, and New Mutants.  I've actually been enjoying the supporting cast of X-Factor quite a bit...Rusty, Skids, Boom-Boom, Artie, and Leach are a fun crew to have bouncing around the stories.  And I've been waiting years to read these early Archangel stories.  I even enjoyed the Bird-Brain arc in New Mutants, so we'll see how that title goes from here on out. 

There's a two issue "X-Men: Spotlight on the Starjammers" mini popping up in my reading list soon...anyone know if it's worth reading?
