under the cymbal will give a heavier kind of sound usually. on top will give more stick attack and articulation. if i mic under a ride i use a ldc a foot away give or take, and generally use in a mix laid back to fill in the space...not an upfront kind of thing. if i mic on top i use a sdc about 6 inches away pointed at the bell. great bell attack then. depends on the playing style, the song, etc. but that's a great ride and will record great.
