A Neumann U87 sounds great on lots of things, which is why it's as ubiquitous in studios as the 57 is everywhere! I wish I still had one! I have a TLM-103 and its good but just not as silky sounding as the U87...
Apart from that I have a pair of Rode NT5s which are pretty good general purpose mics, esp when used as an XY pair.
Haven't tried KM184s, anyone compared them to KM84s?
