You'll probably enjoy the 20-25 Hero and Villain arcs, like Special Agent Nance/Adair's clone arc, Roy Cooling's mediport conspiracy, Dean McArthur's and Vincent Ross' SAs.. Lots of good, cinematic and/or interactive stuff in there.
Provost Marchand and Mr.G's arcs are also quite epic, although a bit hard to solo if you're not well prepared.
