I can definitely recommend Orchestral Brass Classic, probably the best I've heard from any library. LA Scoring String and Hollywood Strings are definitely at the top but for the price and size of it, I just can't recommend it to the masses. My strings/brass setup is Cinematic Strings, Monster Staccatos, Orchestral Brass Classic, and Mr. Sax A. Pretty much covers everything I need and if I need to strengthen the presence of some of those instruments, I'll just layer/blend it with some instruments from Reason 4.
