Just to make sure I'm getting this right, when we're talking about "the edge of the cymbal away from the kit", we're talking basically about 180 degrees away from the edge that the drummer hits with the stick, right? As for those pics, I don't think I've ever put mics that high above the cymbals...it seems like the drum bleed would become a bigger issue, the higher you get. Is that where the positioning plays a bigger role? I've also used large diaphragm condensers a lot, which probably are worse for avoiding bleed than a more directional small diaphragm condenser...
I'm almost afraid to try spot mics on each cymbal just because it's such a different approach, but it's worth a shot. I'm planning on having room mics up anyway. Maybe I'll love it and begin preaching it on the forums afterwards!
