Are we leaving out the thirds rule? I've heard it explained many differant ways, here is mine... The kik is 1/3, the sn is 1/3, the toms are 1/3. The distance from the snare to the oh's is '1', so the distance from the toms is 2/3's. The distance from the sn to the fl is 1/3 and 2/3's from the kik, on and on.
Silk, if 'a' cymbol swishes, it's usually a refelection off a drum head crossing the diaphram of one of the tom mics.
