I've run the Audix CPS-MICRO (cardioid caps) with Church bodies and they sound pretty good.
I prefer my Countryman B3 (omnis), but if I needed cardioids, I'd give the Audix a try. Pretty good detail, and not as "colored" as the AT853. Nothing against the AT853, but these are better IMO. I'd probably rate them better (more detailed) than AKG blue line (ck9x series) as well.
I don't these would be as good from far back, but for a wearable rig up close, I think they are very good...
