I mix drums this way, I have the drum mix going to a stereo bus, the usual compression on the snare and kick as usually required to suit the song, I also have another stereo bus set up with a compressor, I then send either the whole drum kit or parts of the drum kit to this bus, then mix the two buses together, this is a form of NY compression, or parallel compression. The greta thing about this set up is you can try different options very quickly to see what fits the mix.
