The bad thing about using vocal mikes on drums is they are usually omni-directional and that can cause some hassles. I have used two 4 channel boards, one board for the kick and toms, the other board for snare/ hi hat and 3 for cymbals. You can run both of those boards into whatever your recording with, either as two channels or as one w / splitter. This way you can get actual sound without degregation from bouncing tracks.
