Must have Oblivion Mods

So I decided to play through Oblivion again while I wait for Mass Effect to come out on PC. Problem is, the last play through I ran through was pretty darn thorough, so I want stuff that will makes things interesting and fresh again. So far I downloaded the “Lost Spires” which appears to be a pretty in depth side quest involving the Archeology Guild + some of the texture replacement mods to make things prettier. Anyone else have any other suggestions?
